Works well but as others have said it does not cut the ends. For twice the price there's a complete vaster kit, punch down, crimpers, stripper, and cable tester on Amazon that works much better. I bought it for my IT guy, wish I had bought one for me.
Subtracted one star due to issue (mentioned by others) with cutting excess. As long as you ride the side of the tool with the cutting edge, this works fine. If you do not, you will be cutting lose cable ends.
I'm not a professional and I used this to terminate my patch panel and keystone jacks in my house. It works well and feels sturdy. The casing probably couldn't handle commercial use for too long but for casual use, this will turn out great.
PROS: Works well, feels sturdy. It has a satisfying click
CONS: The plastic of the handle is of good quality but not for everyday use.
