Great for eye convergence
This string provides a means to work on convergence problems. I have excellent vision in my eyes but when I'm tired etc. I start seeing double --especially watching the television. I can see improvement after just a few sessions of the exercises. Hopefully before long I will no longer have the problem. Comes with instructions in English! They just don't indicate how long one should do them. If you get one, practice at least a few minutes at a time.

Itโs just as the description From the selling spot.
The product was just like the description. I felt the paper on how to use this product. Was a little difficult to understand for me.0

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.

Good product, better instructions are needed.
The product itself is very simple - beads on a string and a short page of instructions. The best place to get better instructions for use is on YouTube. There are many excellent videos there.

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 slide and string too elastic (bad design)
Ideally you want a taught rope for your Brock String. Because if the string is too elastic (like this one), the the weight of the beads will cause the rope to bounce. Also, when the elastic rope stretches, the diameter of the rope gets thinner, which then makes the beads slide freely on the string.

Received in a good condition
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!

A good length of string.
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!
