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!

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.

This NodricTrack T Series treadmill is an excellent mid-priced entry into the market. If you’re looking for a solid home treadmill without spending a fortune, this a fantastic option. Assembly isn't too bad - most people will be able to knock it out in under an hour, but it's extremely helpful to have another set of hands for some of the steps, and in case you need to move the box to another room after delivery (it is very, very heavy). The iFIT tech is very cool, where trainers can actually change your speed and incline for you while you're following a class, but that feature requires a subscription. Operation is very quiet and has great cushioning, also the deck is wide and long enough for large adults (I'm a 6' male runner), and it folds up super easily when you're done. All-in-all I'm very happy with the purchase and hope that it lasts me for many years.

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.

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
