We were on the fence on purchasing a high end treadmill. We went back and forth between Peloton/Sole/NordicTrack. At the end of the day, we chose correctly. I had read that NordicTrack has the best library of scenic/guided hikes and runs, and boy do they ever. Between my partner and I, we've gone for runs/walks in Vietnam, Italy, Romania, Tanzania and Hawaii. We've created custom warm up routines that we can schedule on the calendar to get going before a proper run. We've also been able to watch our favorite tv shows and movies while we workout if we're just looking to turn our brains off while we get our steps in.
If you're looking for a plain treadmill that just does basic functions, this is probably overkill. If you're looking for extra content and guided runs and walks, the 1750 will be exactly what you're looking for. All the iFit extras are what make this machine great.
Some positives:
Hardware:
The manual adjust for elevation and speeds for guided workouts are seamless and quick. The speed adjust on elevation is especially impressive compared to some other models I've used. The treadmill itself has a great "cushion" on impact for running. Very easy on the knees. It has a solid base and feels firmly rooted to the ground.
Software:
Love the extent of iFIt workouts and trainers. The search features are great at finding you new workouts with new trainers/locations. The ability to listen to music (whether Spotify or Last.fm) gives your workouts an extra level of intensity when you need it. The ability to watch Amazon or Netflix while walking/running is also great. The video and audio quality is great, and Bluetooth works pretty well with our Airpods.
Some things that could be improved on the software/hardware side that would make it 10x better:
Hardware:
USB slot on the side: If you rest your hand (to brace) while using the menu, I'm often getting shocked by the UBS slot. It's pretty annoying, but it's not a deal breaker at all. I think moving that to the bottom where you wouldn't necessarily brace your hand would be a better solution. One additional annoyance is that Bluetooth gets "hung up" sometimes and it just won't connect. I've learned to turn on the machine and get logged in before putting my Airpods in. This has caused me to have to break previous habits because I normally put my Airpods in before I workout. The easier fix I've found when this happens is to hit the power button and wait a few seconds.
Software:
A separate slide adjuster for Spotify so I can listen to my music while going on a guided workout. The volume is identical for the trainer and Spotify so I can't hear them over my music. Means that I have to resort to last.fm. Last.fm has the separate slider. Not a deal breaker, but would be a small change that would be very nice.
The ability to "link" workouts. I have a programmed warmup and would love to link workouts together without having to go through the cooldown and summary and then manually queue up the next one.
All things considered, a great piece of equipment that has aided me in losing some serious weight over the last month.
