Instructions were not included as specified in the product details. Disappointing

The string quality is excellent. The beads move freely enough when you want to move them but stay put where you place them. Simple eye tool that is very well constructed.

Beads unfixed. No loop for fixing or holder. Just a piece of string and 5 beads. Disappointing.

Honestly, it's amazing as a cheap eye convergence device. helps me a lot with my problems. Deep down I feel really petty about wanting to complain about how my mom when I was younger refused to get me one of these. Like dude, they're so cheap too. It trains the part of your brain that moves the muscles very well.

Was great for my recovery. Had a traumatic brain injury and it really messed up my vision. This was great therapy
