The T10 Treadmill from Nordictrack is an awesome upgrade from the 20 year model we had. They are sturdy, reliable and overall, well built machines. IFit, on the otherhand, is comparable to the bloatware loaded on phones and computers. In a never ending race toward subscription eternity, Nordictrack requires an iFit pro membership to use regular subscription fee apps on their system. On top of that, their membership is about $40 a month. You'll need paid subscriptions to Netflix, Primevideo, and/or Spotify in addition if you wantntonwatch those. You can still use the treadmill without an iFit paid membership but I wonder how long that will last.I use an android tablet slung over the treadmill screen if I want to watch videos or use my phone and wireless earbuds to listen to Spotify. Nordictrack would be smart to make these apps free to use on their system. Next time someone asks my opinion about Nrodictrack equipment, I may be more inclined to tell them to shop around for a brand that is less inconvenient. Overall, it doesn't diminish the quality of the machine itself. But a company that creates inconveniences for those that don't pay, that are easy enough to get around, you have to wonder how long until they disable your machine for a fee. It certainly "updates" itself enough. Just my $0.02. Again, an excellent machine that does the job well at a decent cost. Just don't fall prey to the extra expense of the gimmicks.

Easy to set up and start using. Great display that doesn't distract from your workout. I love the aux port so I can listen to audiobooks through the speakers while I walk. It isn't overly loud (though it does make noise) and even at my age (late 40s) it doesn't hurt my knees to walk for a long period of time on the machine. I like the handles and plan to use a mobile desk option to get a little work done while on it. The base seems long enough to do that. It's sturdy and stable and takes up less room than models meant for a fitness center. Great value for the cost.

Very happy with this purchase - overall well-designed, the belt is smooth and nicely cushioned, and the controls are easy to use with a nice set of options for different workout types. The single-press speed and incline settings are nice to have, and I had no trouble connecting the console to the iFit app on my phone, but it's apparently not possible to connect to it via Bluetooth to play my own audio through the build-in speakers (it does have an aux jack however). As for noise level, I don't find it any louder or quieter than other treadmills I've used. As far as setup goes, be aware that the box is extremely heavy. I'm an average height and weight male and was just able to drag it into my house through the garage from the driveway where it was delivered. So I would say that the additional in-house delivery service is necessary if you don't have a couple of strong people to carry it. I'm fairly handy and assembly took me about 2 hours, but I wasn't able to complete the final step (installing the storage arm under the unit) as there is no safe way to hold the base up while working on it alone (I don't plan to use the storage option anyway). Note that it doesn't come with wheels, so I recommend assembling it in its final placement or getting some furniture sliders if you think you'll need to move it at all. Because I didn't see it in the specifications, I'll note here that the height from the floor to the belt is about 8 inches, if you're concerned about head room due to a low ceiling, as I was. One last thing - the unit won't operate at all unless the safety key (magnetic red plastic box) is in placed on the console, so if you turn the unit on and it does nothing but beep, that is the reason.

I had a commercial size NordicTrack I bought in 2015 and it finally conked out on me after using it 5-7 days a week running or walking on inclines. I would be on it for 30 mins or up to 2 hours depending on what I was doing. I got this smaller version because I know how difficult it is to move the monster size ones. Fits nicely in a corner. It is a good size and can fold up. It does not have all the extra features such as a built-in fan, but so far so good. It does have a weight limit, and I don’t remember if my previous treadmill had one. It works with iFit, which is a monthly subscription for $40/month. I think it’s worth it, as it works with your treadmill and provides other workouts such as weight training and yoga. I have been using it for moderate walks on an 8% incline while watching on my iPad (secured on the treadmill). I notice that I break out in a sweat as much as I do when I do a jog. It was fairly straightforward to build except for the part of securing one piece. You’ll know what it is when you get to that part of the assembly.
