Here's a look at the Copper Overdose clone from Fasttech. We'll look at it, compare it to the Copper Cartel clone from Infinite which is 2-3 times the price. We'll do some voltage drop testing between the mods and see if you can find a mod for around 20 bucks that is hard as hell. Spoiler alert: I like this one, but it does require allot of cleaning up of the threads and contacts to make it work as good as it possibly can. I use wire brushes, a pointed end pick and scotchbrite pads to clean the threading. The metal polish I use is made by Twinkle and it's the silver polish. Thanks for watching!
