Already contacted them and waiting for a response, but was curious what you guys thought. Purchased the above 2 weeks ago and it is already autofiring on a regular basis. Also, wattage goes up by itself from 50w (my usual vaping wattage) to 235w and trying to unlock the screen is a nightmare. Sometimes the screen looks all messed up and the numbers and letters unreadable. Any ideas as to what is going on? Thanks.
