I did see a youtube video and the reviewer had the black IPV5 and he was wiggling the door down with his thumb. I can move my battery down slightly with my thumb but it is nothing compared to my Sig 150TC. You have to be purposely trying to move the door down with a little force for it to move.
I agree
@VaporCarp , The IPV5 is a genuine deal in the $60 range. I was out all day and took my RX200 with me as it had fresh batts, first thing I did when I got home was grab the IPV5. Not that the RX200 is bad in anyway, I am definitely not getting rid of mine, just that the IPV5 has a slight edge in performance which I miss when I am using my other mods.
The only con I have found so far was I was unable to change watts once yesterday, couldn't figure it out. The fix was I just took a long drag since it was still firing at the watts it was set at and after that the up and down buttons responded. I was messing with different watts and clicking around a lot to find the best settings for the TFV4 with the triple coil when it happened, maybe I pressed some combination and put it into up/down lock mode?
Right now the IPV5 is my favorite mod although the Brush Stainless Steel Stout keeps batting its pretty eyelashes at me so I have to pick it up too.
