These are heavy duty pliers. I use dams, sinks, wire strippers and crimping tools all day every day. I have all the Snapon tools that I didn't want to take with me to work. I bought these tools thinking they were 3 in 1 but once I started using them I noticed that they don't fit together perfectly so some sizes can't strip that wire. Forces me to zoom out to remove the insulation. Not that big of a problem, but it can actually damage the copper strands. Real cutters are well built and heavy, making it very easy to cut thicker items, but they are regular and not flush. The final piece is the crimping tool that sits between the two handles. It would be really nice if the crimping tool was up where the cutter was and if the tab itself was thinner it now crimps more than half of the connector so you have to be careful. where you actually installed it for crimping. Overall I'm happy with them for what I paid for them, but I wouldn't buy them again for everyday use. They would be good to work alone or as backups or in a home toolbox. But professionals have to solve some quality problems before I can recommend them to colleagues.
