CRP1096 PEX Clamp Tool Kit: Wow this tool worked perfectly and came with plenty of clamps to install. Twenty 1/2″ and ten 3/4″. I used one 1/2″ clamp per connection which was perfectly adequate with the barbed brass adapters I sweated on. No leaks and do not expect any. See pic.

Purchased this as I also had the iwiss one. But after using that one and realizing I needed to remove a clamp. I was trying to remove it with a screwdriver for awhile. Ended up finding this and purchasing this one since this one comes with the removing option. This is great! I opted for the package version since I also needed the cutter. All in all, good price for a good product. Definitely would recommend if you are starting out. Cutting clamps can be difficult and requires some leverage.

Very good crimper for the money. Very happy. I prefer this 6 side version over the 4 for most applications. This crimper is perfect for the listed wire sizes.
For those saying it is too small I can only assume you are either NOT using ferrules (as in trying to use it as a standard wire crimper which will NOT work) or you have insanely large ferrules.

Let me be clear – this is for the little ferrules that go on the end of a wire to insure better connections in screw terminals – typically fond in control boxes or panels (and sometimes in breaker boxes when stranded is used)
This is a great tool and does exactly what it was designed to do – crimp ferrules – no frills.
