I bought this for an office network installation. Before using this I had a cheapo manual tool to punch down. I've never used a punch-down tool like this before. It took a few tries to get used to, but once I got it down, it was easy and a great tool to have. As I said in the before, it would frequently NOT cut the ends of the wires off with the cutter, but it could have been due to user error.
Also, I wouldn't consider this a con, but I found that I needed to punch-down on various surfaces. In my case, it wasn't a problem to use the concrete floor, because the office wasn't finished yet, but in a couple of instances I needed a hard, flat surface. It would recommended to have some sort of portable flat surface that can be damaged that you can do the punch-downs on top of to avoid ruining any floors or walls or desks.
PROS: - works well - adjustable - has pull-out tools on the side
CONS: - didn't always cut the end of the wire off, but I may have been using it incorrectly
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.
