Very good, I bought it for my girlfriend who is a beginner and can't do pull-ups, it helps her a lot.

I have been using it for over a month now mainly for muscle ups and I am very satisfied. I had tried other brands in the past but they did not last.

Honestly, if I hadn't bought it, I would never have done pull-ups. They helped me do my first pull-up. If you are beginners, you should buy it. Start with the blue one which is the hard one and then move on to the green one because it is a bit more difficult. I had bought both to see the difference and then worked with the one I knew better. I recommend it with my eyes closed.

I bought it to help with balance. It does its job and very well indeed. Just if someone is a beginner in pulls like me and weighs over 90 kilograms, they will need a harder rubber.

Very good to start from scratch. I have it for 2 years and it shows no signs of wear so far!

Update 9/2022: After 4 years, it broke, but maybe it was my fault because I tightened it without "warming it up" first at all. Even cut, of course, you can still do many exercises.

Very good for a start, it definitely takes some time for me to be sure about its durability and if it maintains its original shape as it does now!

Very good and high quality. Aestheticians will especially appreciate it, as it can be useful for learning skills such as the front lever, planche, etc., in addition to the strengthening aspect.

Very good, powerful, and sturdy. I use it for calisthenics and it is much more useful than I expected
