Review on TEKXYZ Boxing Reflex Ball Family Pack: 2 Adjustable Headbands + 2 Novice Reflex Balls + 1 Veteran Reflex Ball + 1 Boxer Reflex Ball and Additional Features by Carl Movahed

First off, let me say that my hand-eye coordination is SIMPLY GOOD, but when you hold a bouncing string in front of your face it kinda defeats the purpose! The rope not only jumps constantly and gets caught on my glasses, I also measured on my Apple Watch. It's so gross I can't even. There's a reason nobody has posted a video of them actually using this product and there's a reason. Maybe if you don't have glasses. but don't expect this gadget to work like a video. I will let my son try this first but I expect it will be returned sooner than I opened it
