LFGUD 10T Hydraulic Crimping Tool 12-2/0 AWG Battery Cable Crimping Tool 0.43 inch Stroke Hydraulic Lug Crimper Electrical Terminal Crimper with 9 Pairs of Die Sets

The dies are a little lose fitting, but they kind of have to be so they don't hang up when compressing. I added about 6 layers of blue masking tape to one side of the dies and trimmed off the excess to make it fit the channel more snuggly, but still freely. This kept the dies straighter during compression because I can be particular about appearances. Otherwise it performed perfectly. It does take practice getting into good habits to line it up, but its easy after that. It's a little heavy when you're working up in the air, but it has to be so why complain. Tip: on your first crimp, lightly pinch your fitting in place between the dies, just enough to hold it and not crush it. Then put your wire in and pump until the resistance is firm. If you have to crank down on it, that's too much. It's hydraulic like a jack, go easy and don't crush your wiring to the point of cracking or fatigue and you'll be golden. The end release could be better, but for the price it's a great tool. Glad I bought it.

The dies seem cheaply made, but it worked to make crimps on some 8 and 10 gauge cables. No issues, like that all the dies are contained in the carrying case. The clasp on the case could be a little better.

Works great, comes with repair seals.

I've only made two crimps so far but they were on the largest cable the unit is rated for. It did a great job. It does take two hands to operate but so do the crimpers with the long handles. I have lots more crimps to make. If anything changes I will update.Update:I have now made dozens of crimps and it only gets better. The more I use it, the better my crimps look. Don't let bad reviews hold you back. This is a great product and great price. I would highly recommend to anyone who does even a modest amount of wiring work.

Works fine for the harry home owner/weekend mechanic
