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

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.

Instructions Have colors of beads in a specific order that doesn’t match the actual string order. I tried to remove and replace beads but had a hard time stringing them. So purchased another also stringed incorrectly. Not sure color order makes a difference but I thought the tool was still effective.

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

Works great, quality string and beads. My right eye that is a bit lazy when I look to the right and I already see improvements after just five minutes of using this, which makes me happy. Seems like the proper way to exercise your eyes to work together so they align rather than just using an eye patch (which I haven't tried, but have heard this is better). This string is a better quality than something I might have tried to make to save a couple bucks, and it's worth it to invest in yourself. Hung it on my door coat hanger and will continue to use this exercise regularly.

When the concussion team told me this Brock rope was going to help my daughter retrain her eyes, I couldn't believe it. It works. The beads are high quality and the rope is soft and smooth. She packs it easily in her back and it never tangles. The beads slide just right. Once rehab is done, we will donate this product to the concussion clinic. It is so well made they probably will have it for years to come.
