I had purchased one of the newer switch mods, the one which takes the 20700s, it was the patriot edition and the speckled paint came off in a few days, then shortly after I noticed the copper threading which screws the top piece on is weak as $#*! and has flaws in it which keep the top from threading on properly. I was not hard on this mod but its been falling apart since day 1. Dont waste your $180+ on some poor quality made mod. I sent them an email and also never got a response, they do not seem to care about the customer.
