There are no instructions on how to assemble it? Was it so difficult to include a sheet with instructions...tragic.

Good construction and enjoyable exercise! The only downside is that the assembly with the rubber bands and the bouncing surface was really difficult and time-consuming (my hands got bloody trying to put on the rubber bands)... But you only do this once and then you're done. It's also practical that you can unscrew the legs and handle for easier storage. In conclusion, I consider it a good choice for enjoyable exercise!

Good construction. I use it as an adult and my child does too. The only negative thing is that it's all black for the little one...

Overall nice, sturdy construction. Ideally, it needs a rug underneath to have a perfect fit on the floor. The handle could be a bit more stable, it moves quite a bit in the high positions. You should only use it to maintain your balance, I wouldn't rely my whole weight on it and I weigh 60 kilograms.
