Man I saw your standrite mod and I was floored! Is there anyway you would sell me such a genius device? I have been searching for something similar to this device with a 18650 battery for close to 2 years and have yet to find one to buy. I would make one from your plans but lack the skills that u have. Please message me back on this as you are my last hope in finding such a similar device. God bless you and your creation!
