I've build this band in my last PC. I used very expensive components, so I wanted to be protected from static electricity. I can report that with the use of this band, I mean no incidents of discharge of static electricity that it worked! It is very comfortable on the wrist, I can say, because I was still very easy to carry and have a wide wrist. The design is very good as you just connect the clip to a bare metal surface on the computer housing and the cord is long enough as to extend in order to to get the freedom of movement of parts and work in the computer without problems. We recommend!
