I just received this today, (6-8-24) and I already can tell how much that I like this machine.I am 71 years old, 5'-11", 190 lbs., I used to be in good shape but not doing as much as I used to, I have gotten to where my joints hurt when I squat, up and down. I used to also exercise, but I stopped that, I am REALLY hoping that this will get me to at least get enough cardio (I know, very little) to get up and get on my treadmill.Anyway, as soon as I got it, I started pedaling away, it is as effortless as one could ever hope, too. I pedaled for probably 20 minutes while I was online reading, and when I stopped, I was surprised.I could feel that it was working on my thighs and my calf areas, it wasn't like I did a strenuous workout, b ut I could feel that the blood was being pumped into places that it forgot all about! :)When starting, I did find out that by pedaling like a bicycle, that felt awkward, so I started pushing the 'pedals' forward, rather than trying to push them down as I would on a bike.If that doesn't make sense, just know to try different ways, you'll get a feel for it, I'm sure.So, with that said, with it being right underneath my computer desk, which I actually have the room for, I can't see that I would not use it. I mean, I'd have to REALLY be lazy to come up with an excuse to avoid it, like I am known to do.Using it, I wondered if it was going to slide, but on carpet, it doesn't, I have not used it on tile. If it does, I would suggest to place a small rug underneath.It does have rubber feet on the bottom, so I am pretty sure it won't slide on tile or slicker flooring.The new faux wooden flooring is usually actually kind of 'grippy', so it should work out well on that.It's as quiet as they say, it makes ZERO noise as far as i can tell.Like I said, it's effortless when pedaling, I have it on the easiest because starting out on the HIGH was just not as fun. It's not like I am a doddering old man type, it's just that I have gotten lazy, that's all.So, as time goes on I am sure that I will creep up the tension, or, not, it really probably doesn't matter.I mean, on the least tension is fine, it still gives you a slight bit of cardio, even barely pedaling, it's not much, but it's more than I'd get sitting here not doing anything.I can see this is perfect for older people, I mean, it's as easy as you can get, and, it will get the job done.The main thing that it is slightly heavy for older people, I didn't have any trouble, but if a person has a bad back or knees, or, whatever, they may need someone to help them get it in the PERFECT place and then just leave it there.Anyway, a long story short, I don't foresee any problems with the machine itself, but if something does come up, I will update this.
