Just a note about the vaporesso Polar firmware v1.05 20180802. On earlier firmware the mod was troublesome to update or get to stay connected while updating. This latest update does indeed fix this issue. The mod readily connects without hitting the fire button and I tried reloading the firmware a second time and it stayed connected the entire time without a need to hold in the fire button. It will make any further updates easy to do.
By the way, remember to pull your batteries out before connecting your mod.
