i am having the worst luck.. got my long lusted after GM alien today, brand new sealed, must be a super early version as i have so much button rattle (+ and -) that it even does it when i simply lift the device from the table or put it down! I also have a massive after click/double-click on the firing bar. It feels so awful to use with every click, that i really won't use it. And of course, i asked the reseller his thoughts, he is a good guy, but i have a feeling he will say bad luck on this one, as the device actually fires and works. It gets even better, my G320 must be an alpha cause it too has horrendous rattle, but get this, the text on the screen is misaligned, so you can't see the info unless you are literally straight on top of the screen. Reseller says bad luck. This has massively put me off smok.. those two devices together are a not insignificant amount of money.. is it too much to just expect a straight screen, a solid fire bar and minimal or even no button rattle? Smok build quality is lower than $30 eleaf mods therefore they should be priced accordingly, rather than high end!
