Not a professional tool,but quite well made.The slotted blade is metal which is a bit improvement on most cheap insertion tools.It has done the job I bought it for and looks as though it will do some more.Recommended if it is not for regular use.
Bought this so that I could fit a new faceplate to my ADSL phone socket, and it does the job of inserting the wires just how it should. No mishaps or struggling, just works.
