Brock String - Vision Convergence Training Tool - Train Vision, Improve Strength & Athletic Performance, and More!

It arrived in a good condition, both the bead and the string are of good quality. The bead also doesn't shift easily so it is great!

This Brock string is much better quality than I expected. It's not medical grade, but the balls don't easily slide around when you're using it; they stay in place. But they are also easily adjustable for multiple exercises. The string is kind of a plastic string material, so it can stay pretty taut, which is necessary for the eye exercises it's used for. It's easy to tie and untie. I just tie it to a cabinet handle, and it works great!

Prodotto come promesso. Ottimo.
