Review on Brock String - Vision Convergence Training Tool - Unlocking Vision, Athletic Performance, and More! by Tyrone Lyons

Revainrating 5 out of 5

Exactly as advertised. The thong is soft and skin-friendly. The beads fit snugly on the cord for ease of use.

The soft thread is pressed against my nose so gently. The beads fit exactly as described so they slide easily and stay in place. go to the doorknob. The guide is helpful.

Pros
  • Great for me
Cons
  • No
