Good quality, easy to use
It’s good. The beads slide easily but stay where you put them. The string is easy to tie and untie. The string can be drawn taunt and bounce is easily controlled.

These beads work at home the same as at therapy!
I was able to use this to strengthen my eye convergence at home as well as I could using the beads at therapy.

Great value
Cheap and does the job for any eye issues if you use it consistently

Cheap price but not cheap quality
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.

Good quality, balls don’t slide easily and string stays taut
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!

Beads are smaller than expected
Had a Brock String for one of my children some years ago. The beads were much larger than on this product, and therefore, easier to see. That can be important for someone trying to work on vision problems. The third bead out in the standard 3-bead set up is light green, which adds to the difficulty of being able to see it. Had to order larger replacement beads. Also note, the beads are not anchored in place with knots. You have to read the instructions, get out a ruler, and tie the beads n place yourself.

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!

Broc strings require patience and consistency of use. This one, unlike most on the market, is actually of a decent length, long enough for those of us training our eyes to see at mid-distance. One word of caution: don’t be tempted to remove or rearrange the balls, as it is almost impossible to thread them back on the string. Good value. Give it a try!

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