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

È utile ma vale un decimo del prezzo che l'ho pagata. Potete farvela da soli

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

The 10 ft Brock String is sturdy and comes in a slim metal box. The build quality is great, but the instructions were only in Chinese—so I recommend watching a video to learn proper use. I’m using it for diplopia exercises, and it works well.
