I’ve had this treadmill for a bit now and I’m using it consistently, not just letting it collect dust like most people do. It’s solid. Doesn’t feel cheap, doesn’t shake all over the place when you pick up speed, and the belt runs smooth. Assembly was straightforward. Took me under an hour without needing to go back and forth with instructions. Once it’s set up, it just works. No weird noises, no lag when adjusting speed or incline. I run a few miles regularly and it holds up fine. Cushioning is decent too, so it’s not beating up my knees like running on straight concrete. That alone makes it worth it.

I’ve had my treadmill for close to 6 months now and it’s exactly what I was looking for. Assembly was relatively easy. The product was super heavy so it took two of us to assemble, and there was one screw where it seemed like the thread was housed upside down on the machine to where we had to skip that single screw, but the product is still extremely sturdy and stable despite that. We opted to not purchase the ifit membership and are still able to enjoy plenty that the machine has to offer in manual mode. It has a great display that shows you visually and percentage wise how far you are through each lap, it’s easy to adjust speed and incline both on the screen and with buttons on the frame, and it gives you a nice summary report with averages after each run. Overall a great product!

I am happy that we picked this treadmill (T Series 5). The compact size makes it easy to find a location where we can keep the treadmill out so that we can use it more often, but still be able to move it to clean, etc. Exercise equipment is more useful when it is out and available. Its minimalist profile is nice because it doesn't feel like it's dominating the room. The performance is solid and smooth and quiet. It's solid and strong enough for running and the incline adjustments are nice. We have it on a rubber mat on top of a hard surface, so I'd expect it to be even more quiet if in a carpeted room. I like the smaller control stand/handrails as it makes the treadmill more compact and less obtrusive in the room. That said, I wouldn't recommend putting all of your weight on the handrails as they might not hold up over time since all of the support is on the bolts at the bottom. These are more to steady yourself if you stumble or to rest your hands, which works for us. If more support is needed, then I would suggest looking at one of NordicTrack's larger treadmills. Our kids' friends treat them like parallel bars, so we have to pay attention when we have company. Also, note that the track width is narrower than the larger units. This works for our needs but keep this in mind if your gate is not as steady as it once was as there isn't as much side-to-side step area as on the larger treadmills. Overall, I am very happy with this purchase, and I am glad that I didn't we didn't go with one of the less expensive "off" brands.

This is a very nice treadmill at this price point. It was relatively easy to assemble and has been used pretty much daily over the last 4 months. My daughter runs cross country and track and uses it when she can't get outside and/or wants to do a quick training run. I've also used it on occasion. It is simple to use without distracting buttons. It will sometimes activate when turning it on, which is a bit odd, but other than that we haven't had many issues. I'm giving it four stars instead of five just because it doesn't seem as sturdy as commercial treadmills I've been on, but it still fine for home use.

This is a great treadmill. It is the first treadmill I've ever owned, so I did a good bit of research before the purchase. It fell within my parameters of good quality, not overly expensive, and not a crazy amount of features to worry about. It's a very sturdy machine. Two people are needed for assembly; if you follow the directions, it is easy, just take your time when you go through it. I walk on it every day (sometimes some light jogging) using various speeds and elevations, and the functions work well. The ifit programs are great; I have not used it in "manual" mode yet. It is large and heavy, so make sure you assemble it where you want it because it's not easy to move after. I don't fold mine up because it has a dedicated space in my basement. Overall, I am very happy with it and would recommend it.

I bought this for my mother, it arrived on time. No issues. I paid for the expert installation, which we had no problems. 15 minutes after the technician left, the thing stopped working. Of course I was at work, so when this occurred my mom did not know what to do. She called the tech back and he confirmed he could not figure out why it stopped. Later that evening I stopped by my moms house to see what the story was. Everything seemed to work except the belt. Now I have to call NordicTrack and see when they can send someone out. Amazon, is pretty good about offering solutions as far as returns. I was given 3 options. 1. Call Norditrack 2. Have a local repair person fix it, and they would refund me $120.00 3. Complete refund on both the unit and shipping (I would assume the 3 year maintenance plan). I am giving this 1 star because despite some of the good and bad stories, there should be no reason why this thing should have died. I am hoping I get a quick response tomorrow and we can work from there. I will update as we go along. ***************UPDATE So it was initially decided that the motor was broken on the machine by the technician who was dispatched about a week later. It took about 2 weeks to receive another motor. Add a few days to dispatch another tech at this point we are talking almost a month since the machine has arrived. (I was actually contemplating of just doing a return because it was nearing the time to pay the charge on my credit card.) Back to the story, so the tech shows up, we have the new motor, and an excited mom, I then find out that its not the motor, but the control panel. Again back to square one, another 2 weeks for delivery. Again a couple days to dispatch a technician once the part arrived. Tech arrived installed the new control panel and the machine runs, and hasn't had a problem since. Its been working with no issues for about 2 months now. Mom is happy, but I'm not really sure it was worth it. At this point I can't recommend purchasing this unit through this sales channel. Amazon was perfect but I don't know if it is Norditrack, the warehouse who holds this equipment, XPO who ships this equipment, the tech who installed this equipment... bottom line... a product was purchased for over $700 and it didn't work for almost two months from the day the transaction was completed. We weren't given anything for our troubles. Yes we weren't told "oh well sorry no refunds, all sales are final", we were offered a refund of $120 if we decided to let Norditrack off the hook and go with a local repair person, but there was nothing saying "we are sorry for what happened, the month and a half that was lost will be on us" (the company that failed to delight you as a customer). The only power as a customer is a review, to forewarn others of such an awful experience. I work in the customer service industry, so I know how hard it can be to please customers. In this case, the product offer and the services to support it were abysmal. Sincerely, Sam K.

My wife and I found that we weren't getting the exercise we needed and decided to buy a treadmill. After much research and visiting stores to try them out, we decided to buy this NordicTrack T Series 6.5. We had the Amazon team assemble and set it up and they did a great job. The treadmill was simple to use and the display panel easy to read. My wife likes the versatility of the programs, so it never gets boring. The controls are intuitive and I found that the movements (starting the belt and using the incline) were smooth. The fact that it folds ups to a fairly small footprint was a bonus because it allowed us to place it in a spare bedroom so we could fold it away when guests are staying. It is very sturdy and I believe this will last many years. This was a great choice for us!

I've owned the NordicTrack T Series treadmill for about eight months now, and I genuinely look forward to using it every single day. Setup & Build Quality Assembly was surprisingly straightforward though I had it delivered and assembled. they had it up and running in under an hour with just the included tools. The frame feels solid and sturdy, with no wobbling or creaking even during intense interval sessions. It folds up easily when not in use Performance The motor is impressively quiet for the power it delivers. I can watch TV or take calls without cranking the volume, which was a dealbreaker with my old treadmill. The belt runs smoothly, and the speed transitions are seamless — no jarring jumps when you adjust pace mid-run. The incline feature is where this machine really shines. Going up to 12% grade has completely transformed my workouts. iFIT Integration The built-in iFIT compatibility is a game-changer. The guided trail runs and studio classes make a 45-minute workout fly by. The instructor-controlled speed and incline adjustments keep me honest and push me harder than I'd push myself. The display is crisp and responsive, with no lag. Comfort The cushioned deck genuinely reduces knee and joint fatigue compared to running outdoors on pavement. After longer runs, I notice a real difference in how my legs feel the next morning. The side rails give me confidence during high-intensity intervals or when I need a quick break. Value For the features you get — motor quality, iFIT, incline range, folding design, and cushioning — the T Series is exceptional value compared to competitors in the same price range. I've had gym memberships that cost more per year than this machine. Bottom Line The NordicTrack T Series has made consistent cardio a realistic part of my routine. No commute, no waiting for machines, no excuses. If you're serious about building a dependable home fitness setup, this treadmill belongs at the top of your list. – Verified Purchase
