Sorry for ressing an old thread but didn't see the point of starting a new one for an oldish RBA, Just a few thoughts of mine on the Pioneer Insider which i have had quite a while but didn't seem to get on with. I put a build in it about a week ago and started using it, the Liquid i was using wasn't very nice but the Vape with the 1.2 Airflow Pin actually felt nice and smooth. I decided i couldn't take any more with the awful liquid so decided to put a new build in it. It took me the best part of an hour to build this time round, shaky hands and poor or failing eyesight didn't help, i bought some magnified glasses which helped me in the end, The post holes on it are tiny or to me they are. Anyway build went in and put some Manabush Chiricahua Reloaded in and the vape is excellent and now i can't understand why i disliked it. For me it's easy to build apart from the tiny post holes which i did admittedly struggle with i am finding it among my top RBA's i have. Really enjoying it, if you own a Boro Device i would definitely recommend getting one if you haven't already, it's top drawer for me.
