Excellent core workout tool! This is surprisingly hard to grab. I bought it with the fantasy that I could double dyno on/off the hold. Ha! There's no way that's happening anytime soon. This is a challenging device in all the right ways. If it's in your budget, I'd suggest getting two. It's especially hard to hang from both simultaneously.
I ordered one in pink and the other in teal. Also purchased the UFO in grey and tri-missile in white. This was to create a space theme for my kids. We call the pink cannon bomb Mars, the teal one Neptune, and the tri-missile Apollo 11. My kids love it!
