  • Super sleek and slim/compact treadmill that really folds flat! Super sleek and slim/compact treadmill that really folds flat!
BEAUTIFUL AT-HOME TREADMILL: Been looking for a streamlined, foldable, and dare a girl dream, attractive electronic treadmill for a long awhile...I literally googled 'attractive treadmill'—apparently, it's not a thing. ;) NOT GYM GRADE, BUT STILL BEAUTIFUL AND FUNCTIONAL: I used to have a workhorse of a treadmill that despite its utilitarian/gym-grade design and girth, it kinda sorta folded flat, but at more of a distinct angle due to the overall real estate the control panel, base, etc needed...ya know, like most of the 'fold flat' options. Flash forward to today where, living in a more limited space with no dedicated 'gym room' to be had, I wanted something accessible but easily folded up/tucked away within a dual-purpose space. Now, this little beauty when folded up is lighter and more streamlined and super easy to wheel around (as long as you feel strong enough to lift one side to make it upright first (and this middle age, relatively out of shape woman can easily do it) as the folding flat process is two-fold: First, you release the control panel/handle section to fold it down flat onto the treadmill belt resting on the floor. Then, you lift up one side of the treadmill and voila, you have a truly standing upright and flat treadmill that you can maneuver and wheel around fairly easily and store vertically without it needing to lean on anything. Yay! (Disclaimer: I know the manufacturer states it needs to lean on something, but, thus far, that has not been my experience.) REASONABLY PRICED/LOVELY DESIGN: I was nervous when ordering it, because although fairly reasonably priced, it's still north of $800 when all is said and done, and I have a strong, and ok potentially unrealistic, expectation for what I was looking/hoping to find...happily, I can report it's pretty damn cool. I even like the subtle pink color...not too pink, but just enough to soften the look vs having to settle for the standard black/silver gym equipment. I set it up in my living room (boy, was that box HEAVY, even just dragging on ground from my front door into my livingroom took some doing) and I gotta say the machine is attractive open or close, especially at such 'low' price point for what's looking to be a decent treadmill. SOLID FOOTPRINT: Please note I've only had it for a couple weeks, and haven't done any hardcore running on it yet, but so far so good. :) I call it my baby treadmill, but it doesn't feel too narrow or small for a decent jog, but I'm only 5'2" and just getting back into shape so we'll see. That said, it's looking to be perfect for what I needed: a compact, attractive, foldable, but solid machine for daily light jog/run..sure, .I won't be breaking any records on this one, but it's getting me up and moving so I'm happy. As far as testing it out, as of this writing, I've been starting with a 15-30 minute steady paced walk (3 mph) ramping up to 3 min jog/sprints up to 4-4.5 for a 45-60 min session in total and, so far, the machine feels solid, the only weak point being my currently limited fitness level. ;) No treadmill shaking or noise issues with either incline or speed either. Granted, I do turn up the volume on the tv more than usual when running and the elevation options are limited, but effective (incrementally up to 12), and some of the programming buttons are not intuitive...something to keep in mind if that matters to you which kinda did to me, but getting over it as I slowly learn what each do (ie: reading the manual). In short, for someone looking to get a little cardio going without committing to a much larger or pricier gym-level type machine, this one works really great..and doesn't look or feel as budget-friendly and compact as it is. Very happy! Bravo Asuna. :) ASSEMBLY: This too was a breeze, and basically a non-issue, so much so I cancelled the professional assembly appointment. The only assembly caveat being if you want the secondary handles installed (heart rate handles already attached), just know that you apparently will have to remove them every time you want to fold it flat (at least that’s how I interpreted the manual) which was the main reason I bought the fabulous thing in the first place (ie: ease in folding when done) so I opted to leave the second handles off and, so far, do not miss them—at all. The hardest part of 'assembly' was me trying to deadlift the 140+ lb machine out of the box..fortunately, I figured out a smarter work-around (desperation breeds invention, does it not?), dismantling the box around the treadmill and pulling it out from under the machine...much easier! Also, a big THANK YOU to the two Amazon dudes who hauled the box up 17 steps to my front door. I wasn't here, but saw what their heroic efforts on my door camera. They even called me upon arrival. They are seriously delivery rockstars! Bravo Amazon. :) EARLY REVIEW...so far so good, but if I have any issues, I'll be back to update this puppy. Healthy running everyone! ... show more

  • Awesome treadmill with incline and folding Awesome treadmill with incline and folding
Color: Gloss Black
I've had this treadmill for a week and it's worked great both for inclined walks and level running. My partner is around 180 lbs and has longer legs than I do and is able to comfortably run on this track. The assembly was easyish. I did it by myself. Warning: they say not to remove the strap around the treadmill until you are close to done with assembly. I accidentally cut it because the note not to cut it was tucked under the strap and not visible until I cut it. But it didn't really impact assembly. The front of the treadmill is on the opposite side from where the console is when you unwrap it. The treadmill comes in a folded position, so if you are trying to put it in place before assembly, you'll want the side opposite of the console facing wherever you want the front of the treadmill to face (the wall, a tv, etc.). You need space for the allen wrench to fit perpendicular to the treadmill so you can secure the side bolts. The allen wrench that comes with the set is 3.25 inches long (both sides) so this is the clearance you need on either side of the treadmill to assemble the bolts at the front. My treadmill was being assembled in a tight space so I had to hand tighten the bolts on one side, use the allen wrench to secure them on the other side, then move the treadmill so I had clearance on the first side to tighten the bolts. The safety guard that you remove in the first step is metal. For some reason I got the impression it was cardboard and thought I'd removed it with the packaging. It looks like a valuable piece of the equipment but it's truly bolted there just temporarily for the sake of shipping. All in all, it took me probably an hour to assemble in an awkwardly tight space, including time to move it myself to the right spot. I'm about 125 lbs and not super strong, so it's not a very heavy treadmill. My last treadmill I never would have been able to move myself. I love this thing. It looks smallish (narrow) but I feel I have more than enough room to run and it feels sturdy when I run. There is a tiny amount of jiggling when you run, unlike the solid stillness of a commercial treadmill, but it doesn't wiggle in an unsettling or dramatic way. I have it set on a foam treadmill mat in a cement garage. I did a lot of research on treadmills and ultimately selected this one for the incline capabilities, the size of the track, the fact that you can fold it up, the smallish footprint, the low price, and the good reviews. I'm super happy with it. I don't have as much time to drive to my gym anymore and this gets me moving every day. I'm super impressed with the quality for the price. I highly recommend it. ... show more

  • Love my new pink treadmill! Love my new pink treadmill!
This treadmill is amazing and beautiful! It arrived packaged with lubricant, screws, and an Allen key. It was basically already assembled. All I had to do was attach the handle bars and lubricate the running band. It works great! It is Super quiet and has some major resistance on incline level one- and that’s cause I usually use level 3 at the gym. It’s perfect for my small space and I had an amazing workout. One mile and I was huffing and puffing. I’m a runner and I can say this treadmill is a good quality buy. Glad I didn’t settle for a cheap one. The only issue i had was the Allen key did not fit the running band screw but it wasn’t a big deal since I had another allen key laying around that did fit. I do wish that it connected to Bluetooth so I can use the speaker function but unfortunately it only comes with an MP3 cord and my iPhone doesn’t have the aux plug. Other than that, I highly recommend this product! ... show more

  • Treadmill is okay, but
Treadmill is okay, but there are better brands out there. I was taken in by it being a pink treadmill, however, the quality was not there. One of my issues was with inserting the safety key and it showing an error code. Since it was beyond Amazon’s 30 day return policy, I decided to contact Sunny Health and Fitness directly, whom I’ve contacted for other products of theirs (Twist Stair Stepper and Hyperextension Roman Chair) in the past, and found that they don’t stand behind their products. Sunny’s CS is a joke. Every time that I’ve contacted them, I have received no help. This time is no different. To get a replacement safety key, I would have to pay $13 + tax, as well as a $15 shipping fee (USPS), which isn’t expedited shipping or Priority Mail, for a part that weighs a couple of ounces and is no bigger than 2 inches long. A lot of companies will just send you the replacement part free of charge, but not Sunny Health and Fitness. Suffice it to say, that I will not buy any more of their products. I do not recommend this or anything else by Sunny Health and Fitness. ... show more

  • I'd give this guy a solid 8.5/10.0
Since the pandemic, everything closed, we got stuck in our house and didn't have many opportunities to workout. Sounds familiar? I got an extra 8-10lbs in this period, so I needed to do something about it. I ran outdoors, but as the winter hit, not much I could do. This was a health saver for me! Literally! Pros: - Very simple design - Easy to use - No flickery, no nonsense - No big screen to get in your way - Very simple controls - Easy to assemble - Sturdy looking (doesn't look like it's going to break on you like Nordictrack) Cons - (reason to knock off a star) only goes up to 8mph / 12.8kmh, so if you're an elite runner, this is probably not for you. I wish it did at least 9mph/ 14.4 kmh - It's pink, but of course doesn't impact my score here (sure, they had a black model, but it was $110 more expensive for the exact same product) ... show more

  • Great for keeping active while working from home! Great for keeping active while working from home!
Love this treadmill! I was honestly worried it would be a piece of junk, but it looks great and feels sturdy. The display is really nice looking and it’s quiet enough for me to feel comfortable using in my apartment (I have it set up in my living room right now). I don’t fold it up after each use, but it is very easy to fold up and roll around if I want to. Definitely worth the purchase as I was probably getting only a couple hundred steps in per day at this point with my gym closed, working from home, and the winter is just too cold for me. I love the incline function as well. Really great purchase! My only feedback is that 1. It is REALLY heavy in the box, so you may want someone around to help you when it is delivered. My UPS person left it on the stoop of my apartment building, and I had to lug it in and up a flight of stairs to my apartment... it was tough! Could not have done it without my partner’s help. 2. Some of the measurements definitely don’t seem correct. The step counter, the calories and heart rate monitor etc. feel like they aren’t very close. I don’t have a fitbit or anything to compare the data, and it’s not a huge bother to me since I just want to move everyday for 45 mins, but if you want accurate data on your exercises you may want to use this with a smart watch to accurately measure. 3. It wasn’t mentally challenging to set up but physically it was just difficult for me to get the machine out of the box and to figure out how to oil the running board. Once I realized the Allen key that the machine comes with didn’t fit the screws to loosen the belt, I just dug an old smaller Allen key out of my junk drawer and all was fine. Otherwise, totally worth the splurge over some of the cheaper, less attractive folding treadmills! ... show more

  • Returned. Gave many electrical shocks and frequently shorted out.
First, the good: this treadmill is compact. Unlike other folding treadmills, it folds basically flat and can be tilted vertical so that it only is about a foot wide. This was key for me, as the layout of our home doesn't allow for something bigger. I was eyeing another treadmill manufactured by Echelon which does something similar, but this one was $500 cheaper (and doesn't presuppose the use of a monthly membership), so I went with this one. Folding is super easy. As other reviewers have noted, it is also a very sleek design that isn't as much of an eyesore as other treadmills. It came essentially fully assembled, which was lovely. But, the bad: first, the way this treadmill is manufactured means that it always is on an incline, even if you have the incline set at 0. I am not happy with this. I jury rigged a solution by putting blocks of wood under the rear legs of the treadmill to make the running deck more level, but I was disappointed to have to do this. I'm not sure that the statistics on the treadmill are reliable -- the step counter for sure is not (based on counting my actual steps), and the speed feels a bit slower to me (based on my outdoor running pace and prior runs on commercial-level treadmills) than the display says. More importantly: this treadmill delivers electric shocks most of the time when you touch the buttons on the handles to adjust the speed or incline. Not only are these shocks uncomfortable (at times downright painful), but they frequently are strong enough to short out the electrical system of the treadmill, causing the belt to stop and the display console to restart. This is not an issue I have ever encountered with any other treadmill I have used. I sent an inquiry to Sunny -- it took them a full month to respond with suggestions like making sure the treadmill was lubricated and on a mat. Mine already was, so they told me to just return it to Amazon. I am in the process of doing that now. I was really underwhelmed with Sunny customer support -- both in terms of their delay and their ineffective response. Do not recommend. ... show more
