Review on Black ATV Thumb Warmer Kit - Heat Demon 210008 with Round Rocker Switch for Enhanced Comfort by Predrag Holman

I gave it one star because of the switch. The instructions say swi The instructions say to drill a 13/16 hole for the switch, it didn't fit. I enlarged it to 1/2" undersized, 5/8" undersized, 3/4" undersized. Finally, I used my dremel with a cutting attachment to make a custom hole that was slowly cut and adjusted It took about an hour of my time to install this switch. I'm assuming the switch hole is about 3/4" metric. Before a seller sells an item on Revain, they need to get them to install it by following the instructions and see if they can figure it out. I hope the seller reads this and responds with an explanation.
