Excellent product, it fit exactly in place of my old electric Jack. Bolts in in the same holes. 35 minutes, Easy and quick to change out or install.

Easy to install - comes with all needed HW.Received a unit with a defective up/down switch, Manufacturer corrected quickly.The lower tube has multiple pin points to adjust for height, or retract further for towing.

Operates good, however it's a tad bit slow and I'm not sure if the weight class or the motor. It fits perfectly it's easy to install. I'm a little concerned about the longevity but we shall see.

So far so good. Easy to install. Lots of power. It is a little bigger than the last one on top. Difficult to get the propane tank cover on.

The Kohree Electric Trailer Jack has been very satisfactory. Installation was easy as the mounting slots were able to match the existing bolt holes while the jack was properly aligned forwards. The single power wire was plenty long enough to hook to trailer battery. Be sure to clean any paint or rust where the mounting ring meets the trailer frame; this is the ground connection for the circuit. The Kohree jack is efficient. I have a medium duty battery mounted to the trailer and using the jack 7 times in the winter only took 9% of battery capacity. The jack is powerful; lifting an Expedition at hookup high enough that connecting the torsion bars on a weight distributing hitch could be done one handed. Very pleased with this purchase.

I bought one of these and it worked intermittently; I contacted Amazon and they shipped me a new one and I returned the bad one. The second jack also worked intermittently. I replaced the power wire in case it had a partial break and checked the voltage, it was fine, ran a heavy duty ground wire to be sure I was getting good contact. I contacted the mfg and the rep suggested I use the manual crank to just turn the jack a bit and try the button again. That did work and 80% of the time I had to use the crank to get it to start. We went on a 6700 mile trip and it continued to not work as expected. Now we are home and its past the 30 day return window, so I will just buy another replacement. The rep had told me they had this problem on other customers jacks. Do not recommend.

Works as it should, only thing about this jack & the one it replaced is that the shaft part is smaller around. Hope it holds the weight ok!!
