Review on Grip Rite Prime Guard 2GCS1 by Justin Woolley

Not a very impressive clasp. I tried putting them on my underbody and was disappointed. They took off well, but when the propeller reached its landing point, it spun and would not go below the surface. It would happen more often. If you try to drive them at more than a slight angle, they always cut a hole. I will avoid them if I have an important construction project in the future.
