I dont know what else to say

I build them at home in my shed, I have a old atlas lathe where I make brass parts to adapt chinese flashlight hosts.
My old models were horrible, and broke often. V2 was improved, but still had issues. I didn't give up, refunded the customers and kept improving. Now I designed my own CC drivers, and make my own parts, and the lasers are reliable and even lowered the price since making PCBs is actually cheaper than buying drivers!
Yes, I will gladly repair the laser. Individual parts are so cheap, and I like to make the customer happy!
Sanwu is great if you like luxury laser, built to perfection, and it will never break. My lasers are a tad jump in quality than chinese lasers, and a good alternative since I offer lifetime warranty.
