Good concept, bad execution - FAB Defense Glock Charging Handle

I bought this to help with racking my slide with a slightly arthritic hand. I shoot USPSA and used this at one match. The handle on the product did not last the first stage of the match. It was gone when I had to unload and show clear. The handle can be removed and switched to the other side and is held in with a detent pin. This is where the design is flawed. There needs to be a set screw, not a detent. However, both Optics Planet and manufacturer offered to replace or return. I chose the replacement and I brazed the handle on with brass. Works great now! If this product had passed a torture test, I would have given 5 stars.
