@HallieDe, yeah, same thing here bought mine as well on 4/20 sale past month.
Question for those more experienced Mighty users. Is it possible to start RMA in this case? Because 45 to max 55 minutes on full charge is far less than advertised 90 minutes. It make me feel somehow no so happy about this otherways great product.

Ok, step by step, start to finish. The herbs that I put in dosing capsules (yes, I use those for keeping oven clear) is very dry, fine grinded, 0,1 grams. Inhaling is long and soft (temperature only falls 2-3 increments in Celsius scale in time of that hit). Between hits there is 15-20 sec. pause. In that manner I keep doing my 10 hits, after that turn boost mode and go from 195°C to 210° for another two hits. That's it session is done. It takes 8-10 minutes (was seeking on my watch). And so another 4 or 5 times, till battery level on display falls to 0 increments. Than I put device for a full charge. And than repeat everything what was written above. I have done this cycle already 3 times, now i'm charging my Mighty for 4th time in last 9 days (that's the time when I recieved it). Device is real and authentic 2018 model (S&B confirmed me that). Using it 2 times a day, in my appartment (place is dry and warm 24/7). Maybe it's really some storing issue in warehouse by seller?
