I've been using it for weeks and overall it's good. It's pricey for what it is, but it's well built as it feels very secure and sturdy but not that heavy.

The auto rebound design is fantastic for me to adjust the level of difficulty. It really stretches my abs as they work. The further I roll out- the harder it gets- so if you want to start easy, or just some light warm ups- keep your roll distance short, and if you want an intense burst- push it a lot further out.

Good-looking, sturdy, and easy to use for my core training. It cradles my arms as I move out and back. Should give it a try.
