OK thanks, that's good to know. Is there a way to change the preheat power, punch, and time limit without hooking up to the computer, because it keeps having problems recognizing the device and i have to plug it in 2-3 times to get it to work. The screen will also show "Warranty Service" and the device won't produce much vape at all, unless I take out a battery and put it back in to turn the device on and off. It seems to also have this problem sometimes after it goes to sleep and i don't vape it for 30 minutes or so. It will show the temp is reached but not get hot and barely produce any vape. But as soon as I restart it by removing the battery power, then replace it, it continues to work perfect and create massive clouds. I'm using 2 brand new batteries that are exactly the same. I'm sure the problem is not from the batteries or the build. Something might be wrong with my chip, or I need to do something to fix the problem. It's getting really annoying having to take off the back plate, pull a battery end out to turn it off, then put it back just to get it to vape right. Have you ever heard of this problem or know how I can fix it???
