It's great quality, sturdy. Instructions not so clear. Had to start slow, was hurting knees at first.

This is honestly a great stepper, I have used it for several days and I have no complaints

This mini stepper came completely assembled. All I had to do was push the reset button on the counter and start stepping. It's very quiet and I like that. I am petite in size and also do to mostly inactivity and bit to age, I have lost a lot of muscle mass. So, this is a perfect way for me to build up again and keep in a healthier state. The resistance on this is very good and for my approx. 88 Lbs. it may give more resistance than say a person who weighs 100+ Lbs. I'm only guessing and not sure if weight matters on the resistance level. Since I'm just starting out with it, I use a little "less resistance" by not stepping the pedals all the way down, and only go half way. So, for those of you starting out like me, that may be a better route for you to go until you build up more strength. The one flaw that I noticed was the instruction manual, which was written in English, but made no sense. It came with a couple of tools and a small bottle of oil, but no instructions how or where to use them. It talked about thighs going numb and very odd things like that. I read some comments that said the instructions were easy to follow, so I don't know what instructions I received. I'm just grateful it was easy to use without instructions. It takes up very little space and can fit nicely in a corner. It's sturdy, but also relatively light weight, which makes it easy to move from one place to another. I'm glad I made the investment for better well-being.

The instructions that came with were easy to read and follow.
I will be building up to using this at my standing desk for longer periods of time, and it will be a process, which is a good thing, but I'm actually very shocked by how good of a mini workout it actually is, and if it can help me get more exercise in during the nighttime, when it's too cold or rainy to go outside.
When I first tried it, I felt like the movement was rough and bumpy because it was, not stepping on it correctly with shoes"¦. but with shoes I've mastered the right way of stepping, it's a decent workout and I can feel it in my legs, especially my calves and thighs! The trick is to not let the heel go all the way down and hit the floor"”step up before it hits and then keep going for a smoother stepping experience; a smaller stepping experience is truly achievable. It's not as smooth as an elliptical, but it is what it is and it's right here at home and not in the gym, so there's that. I cranked the adjustment handle all the way in so that the step goes as far down as possible for the largest range of motion.

This also comes with resistance bands that clip onto the front of the machine to add upper body resistance.

Just Right. I put together in about 30 minuted. Everything fit just right. Came mostly assembled, I only had to add the handle bars.
