Review on KOOTANS Decorative Accessories Connector Extrusion by Guillo Tilden

The anodized layer on it is very thick, I found that for use it may be necessary to use a step drill and redrill the holes, normally a drill press would be my ideal tool for drilling but a work clamp and a hand drill are safer to use, in my case I injured my thumb trying to work on the drill, lesson learned. Otherwise they are quite well designed.
