Will continue to use the Brock String.
I use this Brock string to improve my sight picture for firearms training. I added a clamp to attach the other end to something and I train my eyes to focus quicker. It seems to be working, I have noticed some improvement in acquiring my front sight faster. Will continue to use the Brock String.

Another product had a comment stating the balls were like spray painted plastic
These are the real thing. Another product had a comment stating the balls were like spray painted plastic, so I opted for this Brock String. Excellent quality - Same as my Occ Therapists. Glad I paid a few bucks more.
