As a first encounter with a home treadmill, I had second thoughts about whether I would fit comfortably (185-100kg). I went for a 3-horsepower treadmill to have a 50-inch width, and it turned out to be more than enough for running at a speed of 10-12. I chose the slim one to have the ability to fold it almost completely and move it from room to room. Ultimately, the volume and weight are such that I really don't want to know how a non-foldable machine would be.
The positives are the stability, the large screen, the many programs, etc. that you have surely read in the descriptions. The feeling beyond all this is more than positive, you have a sense that you can work out on the machine without the stress of it being a small home treadmill. Good build quality. The incline at 12 is satisfactory, and the space around you is relatively minimal without a sense of unnecessary plastic of old-fashioned treadmills. The noise is normal to low, and the shock absorption is good. On the lower floor, you can't hear anything if you are in an apartment building.
As for the negatives, I would mention the very mediocre speakers (although I don't see a reason not to listen to music directly from my phone) and the fact that there is no indication of pace on the screen, only speed. Those who run on the road would want it.
