all three of my manuals plus my manual PT work flawlessly save that occasionally my manual batts stick on...I'm starting to wonder if they have that infamous "cleaning cycle" chip still in them..cause its like once every 3 days or so..which begs the question cause the 901s used to do that very thing. It doesn't hurt anything, just disconcerting once in a while..you take a nice long drag then boom it turns on for a full cycle and turns off, then works flawlessly for a long time again LOL.
Button wise ive had no issues at all, but i'm not surprised. It's a stiff plastic button...which i think is better..but thats new, and odds are the first ones were still gettin the bugs worked out.
If everything that came from china was perfect we'd all be driving chinese cars ...instead of just eating chinese food, watching a chinese tv,
vaping chinese e-cigs and wearin chinese clothes haha.
