## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great..
*by J***R on May 12, 2024*

Only fault I would give it is it’s hard to figure out a system to mount it. The mounting holes and posts for the terminals make it awkward. Aside from that it’s great.

### ⭐⭐⭐⭐⭐ Easy and it works
*by L***E on March 24, 2024*

Installation is extremely easy, simple operate and reliable. Use as added security on my ‘57 Chevy.

### ⭐⭐⭐⭐ Worked well
*by B***O on February 6, 2024*

This master switch works well but the keys are made cheaply and there’s a bit of wiggle room in the locked position, they work though, and for a good price.
