Great product.

It works
It works! The action for the switch is a little loose, so you can twist it past “Off” if you’re not careful

Tried to turn the item, on and off and it broke. Very bad item, very poorly built!

Flimsy backing plate
Backing plate is made from hand bendable aluminum. Any tension and it will break. Not great for nice setups

Nice disconnect!
I am an automotive technician and I felt it is important that this disconnect be able to function without dropping more than 0.1V under a substantial load before i would install it. The video is an example where I pulled a 300 amp load for about 12 seconds and then progressed it to about 450 amps before my weak battery started to drop too low. You will notice the voltage drop was within an acceptable range under a severe load. The only heat produced was in the carbon pile and at the jumper connection at the switch. The nuts being tight on cables should stop it from heating up. In the attached pictures you can see that a 2" hole should allow this switch to mount in place. I will definitely purchase this disconnect if this size is needed again.

Sturdy little switch
Good little switch. Keep in mind it is rather small. Looks very durable.

Effective, cheap in price and construction.
Works, but feels cheap. The knob is loose, the nut is just pressed tin and cuts your fingers, and its very hard to tighten enough that the whole thing doesnt rotate when operating.
