Review on Protorq T15 T40 6 Piece Industrial Strength by Rhett Fifer

I've seen different types of bit holders from Ryobi, Dewalt, Bosch, Milwaukee and maybe a few others. This one is actually very good. If you pull on the racquet to release it, it will rotate a little and then pull it out. Then you do the same thing in reverse order to put it back in place. Bosch bit holders have the same action but work slightly differently. I like Bosch too. As for the attachments, they appear to be of quite high quality and match the appropriate fasteners. I haven't had it long and don't use it very often. So I don't know how durable they are.
