Just an idea...but there are many great mods on the market, but some are WAY WAY WAY overpriced, one mod in particular that is always sold out or on order is the GG, there are several models but if a SMART engineer was to make a similar device with an all mechanical switch...nothing to break....and price it afordably to us peasants they could literally be the next big thing to happen to the ecig market. The GG is not USA made and there is only one distributor in the USA and he is totally happy that he can charge outrageous prices for his device, because they sell as fast as he can get them....that give you any ideas? Another mod that cant be bought untill they make them and they are sold out the day they are put up for sale is the REO....model a mod after that mod and make another big splash.
I guess what Im trying to say overall is, Dont Try and Reinvent the Wheel...take a few of the best wheels make a couple improvements and charge reasonable prices....and become OUR HERO...LOL
PS: Tricky switches will ruin any chance you have of mainstream vapers becoming fans...look at the SaberTouch and get the idea...they dont work (for long)...mechanical switches are the switches most people want to see come out. Like the GG the Alpha The Bronze the Omega...
