Well made works as designed. I installed it on my travel trailer. Only needed one gave the other one to a friend with same trailer and battery set up.

It looks good, but very thin piece of metal holds it together breaks like glass.

This is a very good product as an isolation switch. It took me less than 5 minutes to install this device. The device doesn’t infers with anything around the battery. I am using this device on 2002 Chevy Blazer with 12 volts side post terminal. I will highly recommended this product for anyone who needs to isolate (shut off) the power supply from the battery to the rest of the vehicle.

My battery was being drained by electric devices and now a quick disconnect and I don't lose my charge and have to boost.

I wanted this device to isolate the battery on my Classic American car, hence the need for a side post fitting. Bought another one,great product.

A parasitic battery drain was creating problems in a vehicle - wanting an inexpensive solution I installed the disconnect.My problem / the factory crimps used to maintain component alignment were not tight enough and allowed misalignment to occur. When the knob was loosened off, the component with the bolt hole tilted enough to allow minor contact between the contact surfaces. I loosened off the knob, hit the door lock button and the locks worked, good thing I checked. Easy peasy to fix, turned it on it's side, placed it on the anvil and re-crimped it with a small hammer and punch, totally fine. Do not assume it is disconnected and test before leaving the vehicle. The vehicle I used it on has remote locks, try to open locks, try lights, honk horn, or??? Switch has been installed for 1.5 weeks and as far as I know, all good.regards all

Bought these for my rv. Was getting tired of undoing the leads from the battery after each use so installed one of these and I'm pleased with them.. Just a few twists of the nob and power is disconnected.

Installs easily on negative (always negative!!) battery post perfectly. Put one on each of my F-350 batteries to quickly disconnect when doing service. So much easier and cleaner than removing negative lead off the post each time!👍
