Review on IWISS Terminal Crimping 6 50Mm² Electrician by Chris Endricko

So since it's like a pair of pliers, if they go in at an angle, they'll squeeze the crimp and pinch part of it. The trick is then twisting the crimp and doing it again to compress that part. It's not the prettiest crimp, but it's effective and easy to do. It's also nice to be a hand tool. I have never used hydraulic pliers, many of the reviews I have read on hydraulic pliers say they fail. They're more complex, so it makes sense. It's nice to have their simplicity as they only use leverage as a mechanical advantage.
