[This review was collected as part of a promotion.] I upgraded by 8 or 9 year old Commercial 1750. It is quieter and the incline/decline operates very smoothly. I notice the change in incline quicker than my old one. I love having the big screen is well.

[This review was collected as part of a promotion.] Absolutely 100% pleased with this treadmill. iFit runs with my Apple Watch have enabled me to dial-in my heart rate and optimize my workouts. I love that the treadmill matches speed and incline to the guided videos.

[This review was collected as part of a promotion.] The treadmill is great. It has so many workout options. It is very heavy in the box and putting it together takes awhile.

[This review was collected as part of a promotion.] This model has performed beyond expectations and is reliable, durable, and fun. Paired with iFIT, it has made my fitness journey one to look forward to every day.

[This review was collected as part of a promotion.] Great screen. Cool that the machine changes elevations and speed on its own to follow the video you are exercising to. Transitions are a little abrupt, so you need to pay attention to the bar graphs showing how your workout will progress to know when to transition. Lot of plastic in the construction, which I suppose lowers weight and cost, but feels a little cheap in that regard. But seems to be solid where it matters.

[This review was collected as part of a promotion.] Had Nordic track before and loved it. This treadmill is nice but the training programs do not start and they default to standard walking on the treadmill. It requires multiple attempts and turning machine on and off to work.

[This review was collected as part of a promotion.] A number of things make this feel like it was designed without input from runners: 1) The belt catches a bit, especially at lower speeds. It's good/solid at normal running speeds. 2) The speed is about 10% off, so that if you set it for a 10 minute mile, you'll be running at around a 9-minute pace. 3) The pace/mile only updates every few minutes, not in real-time. 4) The fan is not adjustable, I'm 6-1 and it hits my abdomen. Separately, a lot of the functionality (especially the big screen) is designed around forcing a monthly subscription. Without the subscription, I'm not sure this thing makes much sense.

[This review was collected as part of a promotion.] I was very excited about the treadmill, but unfortunately it's just okay. Connection and app issues from time to time. Membership is too expensive for what it is.

[This review was collected as part of a promotion.] Really disappointed with this treadmill. Chose the 2450 because I need a treadmill that can exceed a 4:30min/mile pace, as I'll be doing speed sessions indoors during the winter. Few treadmills go faster than 5min/mile, 12mph. After the first few runs on this thing, I got some pretty strong buyer's remorse. It lacks many "quality of life" features that, at this price point, are unacceptable. First thing I noticed is that it doesn't even have a tray or ANY horizontal surface to prop up your phone. It has two cup holders and a handle, then the giant monitor. I bought a phone holding device to accommodate this lack of a very simple feature that every other treadmill I've ever used has. The IFit monitor is unnecessarily big, and of course you need a $39/month membership to use ANY of the features. Ridiculous. The most annoying oversight, or just plain terrible decision making, is that the quick-change buttons have an inexplicable gap between 9 and 14 mph. The numbers go 1,2,3,... up to 9, then for no reason at all goes 9 then 14. You have to hit 9, then tap the to get up to any speed between 9 and 14. So stupid. No way to customize or fix this. Additionally, the and - buttons SUCK. They're not analog, true "buttons", they're super finicky touchscreen-type buttons that are difficult to press, especially at high speeds (like when you're trying to get from 9mph to ANY SPEED BETWEEN 9 AND 14). Overall, a major disappointment, especially for the premium price tag compared to other home treadmills.

[This review was collected as part of a promotion.] The whole process of setting up IFit and registering my treadmill did not go smoothly. Once the machine was set up you are on your own. Contracting support wasn't seamless either. I'm questioning my decision to purchase your treadmill.
