I've got one of these. The temp control mode is strange, can't seem to get it into this auto joules mode that they mention in the instructions. Instructions say "left + right button: calibrate the current resistance to get a proper joule automatically" All it does is set it to 60 joules and it cuts out with a dry coil message when you try to vape it. Have to manually set the joules lower to get it to work. More of a temp protection mode than a temp control mode.
Works good in wattage mode. They fixed most of the issues I had with the XVO stick. Screen on the side vice bottom, Atty cage at the top so you can still get at the airflow ring on your atty. Only issue they didn't fix is the battery vent holes are still on the top by you face and they made the dam thing heavier than the XvoStick
Yeah, the instructions don't seem to be completely accurate. The "left + right button calibration" is nothing more than setting the initial resistance when you first install a new coil. By automatic joules, I "believe" that they mean it automatically goes to max (60), but temperature control should kick in before the coil burns ... so I don't think it was designed to auto adjust, for example to 32.5 joules, so I am glad it is possible to manually set the joules lower. Essentially, I think it's more of the ramp up to temperature than an automatic joules setting. The higher the joules, the quicker it will get to your set temperature. Personally, I like a slower ramp up, but I wish the instructions reflected it this way instead of calling it "automatic".
I don't have an XvoStick, so I can't compare the weight of the two. I do agree that the venting should have been a little different. It would have been great if they had mounted the battery tube the other direction, it would have fixed all the concerns with the venting.
