As an Industrial and Scientific buyer, I purchased this product hoping it would make my life easier. As my tests showed the pins are not durable and kept bending. Although they were easy to install, they simply weren't worth the investment..
I've drilled quite a few pinholes with it. I was impressed for a while until it fell apart. The drill bit stopped moving up and down as I drilled holes. I took it apart and put it back together. It worked for a while, but then the problem reappeared. Now I have it piece by piece. I will probably return it.
