Works great

### ⭐⭐⭐⭐ Works well - remember to tighten the bolts after installation
*by G***. on July 18, 2024*

There is not much that can go wrong with this device since it is a simple mechanical switch. I was worried since the construction was a little flimsy but after installation is worked well. The switch arm is held solidly between the copper and there is no danger of becoming "unswitched" on rough or bumpy terrain. I have been using it for 6 months and have no issues except that the bolts are getting loose that hold it together (not the ones that hold it to the battery). You can't simply tighten them when the switch is installed, you need to remove the switch to tighten them.
