I have greenlee hydraulic knock outs and wanted something a little smaller to take out at times. This thing may be the only KO kit I take out now. It’s great!

Bought this in January. Broke by June. I used the tool on 3 or 4 different occasions and it broke at the most recent job. So you can say I used the tool properly prior to it falling apart. Smh. The handle popped off and oil began leaking.

It started out working perfectly, but about after the 4th or 5th time I used it, it just stopped working. I tried all the troubleshooting, but nothing worked! I contacted Amazon and they refuse to accept the return since it's been over 30 days. I know that if I had purchased this at a local hardware store or Home Depot, I'd have a new one already. Definitely something to think about if you are thinking about buying tools (or anything!).
