Bests & Worsts Reviews from Amazon

Awesome, though a few things to note. The lugs on this thing are HUGE. You have to drill out pretty much any connector in order for it to work. Needs abut a 7/16" hole, but the lugs are right at 3/8". You need screws that are about 2.5" long in order to flush mount, and put the back cover on. 2" screws will work, but you won't have enough screw to mount the back cover. Most nuts you find will NOT fit inside the available area for the mounting nut. #10 screws are the biggest you can use, though #6 nuts are the only ones that actually fit. I bought #8 screws and nuts, using a heat gun I heated up the nuts to the point it would melt the plastic, and shoved them in the spot where the nut goes, making them somewhat permanent. I then mounted the switch and bought some wing nuts to secure the cover on the back. I intend to shave off about 1/4" from the screws so they don't stick out so much. The knob comes off by turning counter-clockwise to off, then pushing in and turning another 1/8 turn counter-clockwise. It makes it sort of like a key. Amazon hasn't included any good pictures of this item, so I've added a few more. I bought this to put in a large tool box that I am using to replace the standard single-battery box that is on my RV. I will now be able to have 2 batteries and use this to disconnect between trips.
