OT approved
Purchased for vision therapy at home. Our OT commented that this was a good quality product as the beads don’t slide down the string when using.

Perfect
I love these Brock strings, they are exactly what I was looking for. Unfortunately, I tried to take all but one bead off and now I can’t get any back on. Good thing this came in a pack of 3.

Softball hitting vision aid
I bought enough of these for our whole softball team. The girls are using these in combination with hitting "golf ball" whiffle balls and a sklz power stick to train them to focus more on the ball. It appears to be working really well.

Just what I was looking for. I am a sports performance coach looking to improve visual skills and the Brock string is just for that. Came with three strings. The beads move easily but don’t slide when you hold the string high or low. If you’re looking for a Brock string look no further, this is what you want! Going to be purchasing more soon

Good eye training tool
The product contains several strings that you can use for different eye exercises and leave -- meaning connected to different heights of anchors or lighting conditions, depending on what you need to strengthen. Plenty of stuff on YouTube on how these are used, don't worry.
