    • Excellent tech support from Sunny Health & Fitness, even after warranty has expired
I bought this treadmill over four years ago and have used it extensively since. Unfortunately it stopped working recently and I contacted Sunny even though the warranty has expired to see if they might help. Carlos in tech support was quick to reply with helpful information to help me diagnose the problem. Since I'm out of warranty I had to pay for the broken part but the part was not very expensive and Carlos provided detailed instructions with photos to help me install it easily. Without their support I would have had to either guess at what was wrong or, worse, trash the whole treadmill and buy a new one. Nice to see a company stand behind their product and customers even after so much time has passed since purchase. ... show more

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

    • Good for the price
I've had this treadmill for about a year now. It was easy to assemble; I am not handy and I did it myself with just the tools provided. The heart rate monitor takes a long time to register during a workout and I'm not sure how accurate it always is. It's comfortable to walk or jog on, and it's easy to adjust the incline. (To change the incline from 0, 3, or 6 degrees, you lift up the far end of the treadmill and the hydraulic lift keeps it up; this is also a way to store it in a smaller space, though it doesn't get that small. You manually take out the pins on either side of the edge of the treadmill and place them in one of three holes to get the desired incline. You do have to stop the treadmill and get off it in order to change the incline, it is not seamless. Additionally, the highest incline is still pretty minimal; I'm used to power walking at a 15 degree incline, and this is definitely not that!) I keep it in the usable position and in the same spot in my living room all the time, though if I need to move it it's mostly easy as a single person. Initially I was wheeling it to the balcony every morning to workout so as not to wake up my roommate. Moving it is doable though not pretty, but I'm a young, healthy, able-bodied person (not very strong though; when I weight lift I use 10lb free weights). There are start/stop buttons next to the heart rate monitor, so I've accidentally turned it off before, but not a big deal. The water bottle holder is very shallow and narrow so most of my (reusable) water bottles don't fit there; there also isn't a way to set your phone on the machine to watch TV or even just keep track of the time. (I considered buying a plastic device to set over the screen to hold my phone but ended up buying a big screen TV.) It's pretty quiet in my opinion, though when it turns on or off it beeps three times. I don't think it's loud but my roommate would awaken even by doors opening, so she would hear it. For the price, I'm happy with it! ... show more
