For this amount of money, I didn't expect it to be so poorly made, they fly about 1 centimeter in the air, so they move when you grab them. Also, the tube has a dent at one point. Yes, you can exercise with them, but they definitely don't have the quality of construction that you would expect.

Very good but for some reason they have a slight instability no matter how much I tried to fix them. I think it's because of the plastic on the base of the legs.

For now, I am very satisfied! It will show if they will endure in the future and how convenient they will be... They seem sturdy and of good quality!!!

Edit: after about two years, they have slightly bent in some points, maybe because I had them at the highest setting only and they cannot withstand much weight etc... That's why minus one star!
Nevertheless, if you align them a bit yourself before workouts, you can use them normally!
