TL;DR: CT11Pro – Great elliptical, built sturdy, easy assembly, quiet and smooth. You should consider it.
We purchased the CT11Pro as my wife is tall and wanted the longer 18 inch stride that it provides.
First for all the good things – It was easy to assemble and comes with the tools you need. I assembled it by myself but you'll have to be careful with getting it out of the box if you don't have help. It works very smoothly and quietly and the stride is great. It has a device holder although you'll see in my negatives that it covers up the monitoring. It feels heavy duty which it should if it's going to support up to 400lbs. And the biggest positive of all, my wife loves it (and so do I). 🙂
The only real negatives I've found so far is that I don't think the heart rate monitor is very accurate. I have an apple watch that I compare it to and it's just all over the place. It starts out much lower than what my watch then ends up higher. But, that's why I have an Apple watch so that doesn't bother me. So far, I haven't really used the monitoring much at all so I don't know if the distance, calories etc are accurate or not. It has a device holder but when you place your device in it, it covers up the monitor anyway, especially if you use an iPad or tablet. I do wish that the magnetic resistance dial was higher up because to adjust it you have to bend over and try to see what you are adjusting it to. Makes it a little harder if you are doing a pyramid program or something where you are adjusting resistance several times. Something that you will learn to do without looking though I believe. It has no water bottle holder like some have. The other negative was getting this thing shipped to me. It probably wouldn't be any different than any other large item like this but it arrived way later than it was supposed to and came in a rented Enterprise box truck with 2 guys to carry it in. This might be because we are about 100 miles from an Amazon warehouse so you may or may not have any issues like this.
Even though it may look like my negative list is longer than my positives, they aren't. There wasn't much to explain on the positives. The positives far outweigh the negatives and I would certainly recommend this elliptical.
One other note I will say is that even though you can find reviews and assembly videos on Youtube, it doesn't appear that Niceday has any real workout content out like the competition does but does connect with Kinomap which is interesting as you can choose different routes so you have different scenery. It requires a device and connects through bluetooth to the elliptical computer. It was fairly easy to connect and setup but I haven't yet figured out if Kinomap is only subscription or if there is a free side of it so I've just been using Youtube videos created by others such as Sunny Health & Fitness being one and Apple Fitness+. Surprisingly, Apple Fitness+ or Peloton neither have specific elliptical workouts but you can use those geared for either cycling or treadmill as substitutes. The Apple watch has an elliptical workout also which will get you the metrics.

For the money, this is a good elliptical. It was easy to assemble, it's lightweight and easy to move around, and it's quiet. You cannot adjust the stride on the one I bought, so the title of this item is misleading as it mentions a stride range. If you want that feature, make sure you're purchasing the right one (not the Classic CT11S).
My only complaint so far is that, if you let go of the poles, you are leaning back a bit and it's very uncomfortable. I like to be able to walk/run on it hands-free and I can't really do that. I'm also a bit concerned about the dial for resistance, as it seems like it might wear out, but we'll see how it goes! I needed a cheap elliptical to get myself back in the swing of things, so I think this is perfect for that. I will upgrade to a nicer one if I maintain my routine. 🙂

Ordered this for my bedroom/ office space and it’s the perfect size. Assembly took me an hour and instructions were very clear. No wobbling AT ALL. I still need to test it out so I’ll update then, but this is a SOLID elliptical. Never had one before and hate going to the gym. Cant wait to try it out and get moving! Definitely worth the price so far. Updates to come…
UPDATE: Managed half a mile and even on plush carpet it is sturdy (some wiggle room due to soft surface, but I might find wood or something to place under the bases) VERY smooth and VERY quiet so I can watch my show in peace while I sweat it out! 10/10 recommend!!
