So I got the innokin itaste 134 the other day from DFW Vapor (where they're on sale on their website for $149). I really dig this thing except for one issue. It seems to shut itself off randomly a couple of times a day. I'll grab it for a vape
and immediately realize it's turned itself off. 
Not a huge issue but hoping someone may know why this is happening or have suggestions for remedying it...
