“New v2 chip is really nice. They also added a direct conductor from the chip to the battery it looks like. Should last longer than my old mods. I noticed the screws holding Down the chip to the body corrode and need to be tightened every now and then on the old models or strange things happen. That problem might have been fixed in this new version. We'll see how reliable this new mod is. I've only had it a day. My only complaint is the useless little window showing the ribbon cable under the button. Just a plain square or round button would have been better in my opinion. Heres something though. The plate that covers the chip in the old mod fits right in this new mod so you can have the old round button. Youll have to modify the ccrew holes a bit though. If your into that sort of thing is solid vape mod so far.”
