Top notch quality, super simple components, HUGE screen, transitions up to 12% incline, down to 3% decline so smoothly! I've never looked forward to my workouts, but this is MORE than a workout—It's truly a luxurious experience, as you are completely entertained and challenged while meeting your exercise goals! This is no ordinary treadmill. **This is an incentivized review, but the feedback is my honest evaluation of this product.**

I live in a very hilly neighborhood and running eventually started to bother me knees. I researched best treadmills and kept coming back to this one. So far it has not disappointed. It's in my bonus room upstairs and I run 5 times a week on it. The training sessions on it a very good. Highly Recommend!!

This has been a great treadmill. The hardest part was right at the beginning. It got delivered to our garage and we had to take it down into our basement. I wasn't strong enough to help my husband lift it but with a neighbor's help we were able to move it downstairs. From there it was so easy! The step-by-step instructions made it rapid to set up, about an hour or less. We were able to use it right away. From there the treadmill has been great to use! As a beginner I have been doing the guided walks to start. I love that there is even a beginner walking series just to get you started. The treadmill automatically adjusts speed and incline which helps take out all the guess work! If for some reason it is too fast you can lower the speed and the “Smart Adjust” will update the remainer of the workout. I have been super happy with this treadmill and can't wait to keep using it! This is an incentivized review.

I have only been using a little over a month but so far so good. I love the monitor and locations for background. I've been trying different routines as well. I like the auto adjustment feature. So far I can not get my Apple Watch to connect but will try again

I have been using the NordicTrack Commercial 2450 for about 3 months now. I find the user interface and software flakey. Sometimes after start up, I try to use the touch bottoms to enter a speed on the touchscreen and nothing happens. I have to completely power cycle the system off and restart to gain control of the speed buttons. Durig workouts, I press the speed buttons to enter a speed and sometimes several numbers light up after I only hit one butt with my thumb tip. For example, I alternate between jogging and walking. I be trying to end a 7. 0mph jog and hit the "4" button on the screen to slow down to 4. 0mph. I'll se the '7", "6" and "4" all light up simultaneously, and nothing happens. If I am jogging at 6mph and press 4, the speed goes to 6. This happens at least once every workout. Also, I don't like that I can only use these buttons to go to say, 6. 5mph. My prevous Commercial 2950, I could press 6 followed by a 5 and the system would consistently go to 6. 5mph. This new Commercial 2450, I can only set to 6 and then after go to the arrow button and press the arrow 5 times to go to 6. 5. Very disappointed with the user interface and flakiness of the software.

In only two months having the 1750 at home I have turned walking and running into a lifestyle change, The iFit options have been a game-changer for keeping me interested and excited for the next workout. I also LOVE the built in apps for Netflix, Spotify, and Prime to cover me when I just want to do a manual workout and need some entertainment as a distraction. I couldn't be happier with this purchase, which with the 0% financing is costing me less per month than a gym membership or fitness class cost.

Love this machine. Sturdy and well made. But why would NordicTrack design iFit for only one type of athlete who wants to follow a trainer who annoyingly drones on. I've been disappointed in the lack of flexibility to create "my" workout with interval training and random inclines throughout an interval workout. And lastly that there are no virtual running sessions. I've resorted to YouTube virtual running videos on my TV. And don't get me started with Apple compatibility. Very disappointing when it comes to programming. BUT. . . Buy it for the machine. Wow.

I upgraded to the 1750 when my NordicTrack C990's motor went out after many miles. (We're giving that to our son who can replace the motor. ) I love the 1750 bc of the added decline feature and the rotating screen so I can do off-treadmill workouts without watching on my android. The C990 screen made workouts always seem to be at dusk as it could not be adjusted down. (I'm 5'3". ) I had to get on my tiptoes to see the sunshine in the workouts. Now, I can see all the scenery as it was recorded. Love it!

I would give it five stars if it weren't for two minor things that can be corrected: the responsiveness of the touch screen and the fact that it is not possible to press the speeds in sequence to make a partial speed, like pressing 5 and 5 to make 5. 5 or fibe and 6 to make 5. 6 and so on

I have had this for less than 1 month and already has begun to make loud noises when I use it. I am trying to set up a repair but I have yet to have my treadmill serviced. I am hoping they will repair it. I weigh less than 120lbs, my treadmill should be able to handle daily use.
