When heater unit is on charging stops. You reach your desired temp and charge resumes. You draw and temp drops, heater unit re-engages and charging stops again..... You get the idea.
Have you checked your cooling unit doesn't have a leak in it. Remove and put thumb over the screen area and suck or blow into the mouthpiece. Should be fully sealed.
Crafty is an amazing sidekick to the mighty. I use them in rotation so I always (when I do it right) have one ready to go. Nothing worse than the battery going dead at 158 degrees c!
Mighty is the only way forward for me. Can be a group beast with full chamber/capsule. But can also be a really good micro dose (<0.05g) with spacer/liquid pad in the bottom of capsules.
If it looks new it probably is, even if box has been opened you would know if it had been used by smelling the Chamber. Your warranty runs from 2 years from date of your invoice so I'd say you're safe. Go on . . . . Fire her up.
All joking aside, that might be a viable option. If you can find someone near to you that has a vapcap you could send your one to them so they can test drive it for you .
Use the round end of the orange packer tool to push the bottom screen into position.
I have also managed to position a second screen part the way down to decrease the size of the chamber instead of using the liquid pad.
With Carb hole fully closed and draw as slowly as you possibly can then you should be able to get a really throaty hit with lots of clouds. Then it's a case of feather the Carb to create a cooler hit. The other option I have tried is draw it into mouth then inhale - like a cigarette or joint...
Does your toothpaste contain sodium laurel sulphate? That can cause ulcers. Rinsing mouth with salt water or using corsodyl mouth wash after vaping might help. My dad had problems with ulcers and ended up being fresh tomatoes causing it.
I think the message you got states the machine you sent in under warranty is not repairable so they are sending you a new unit instead. Nothing to be worried about, infact everything to be happy about!
