As you could probably see in my previous review, everything started very well. I got the chip working, every function was exactly the same with original one, I was happy and wrote a very good review. Untill 8-10 hours went by and it just stopped working.... every time I press fire button the chip just restart itself, you can do shit with it. This was last time i order anything more techinical stuff then a drip tip or o-ring from this company... "fast" = delivery to Europe in 3-4 weeks, "tech" = stuff which just do not work... I realise that this review is quite stupid, because it is my own bad for assuming I could get quality for cheap, but people, please, learn from my mistakes, don´t do your owns.
