I owe the Mighty. After less than 5 months of use; 3-4 sessions per day, less than full load using liquid pad to fill heating chamber, temperature set-point 356 degrees without stepping; the unit began to require charging every day. Should be aware that as the level of charge gets below half the heat up time increases. Returned to Storz & Bickel and was told "anticipated repairs would be free of charge". Well 2 days later received an email requiring a payment of $96.40 for the replacement of the batteries ($40.00 x 2 for batteries, $10.00 labor charge, $6.40 return shipping). When I questioned this because of the 2 year warranty, I was told the batteries are wear and tear items, and not covered by any warranty. That chapped my hide and I had a heated discussion with an employee at the repair facility. Ended by telling them to return the piece of junk. They returned it alright, but not the same unit I sent to them. Returned unit was not mine, it had a different serial number and the heating chamber was extremely dirty and covered with brown burnt resin. I immediately called and emailed them about this and was told the serial number label was changed but the unit was the same. I told them it was not the same machine but they insisted it was. So I used it and found this unit did not recognize the set-point temperature correctly, since the unit would always heat up to 360-364 degrees rather than 356. Called and emailed again, and was told the new units work this way, and mine had received new programming update. What???? So the Mighty does not have precise electronic control or super precise temperature control? Sent unit back and when returned was told unit is functioning perfectly. Unit still heats up above the set-point and now I can barely get through 3 sessions before recharging. So for approximately $400.00 I got a vaporizer that worked well for 3 months, needed new batteries after 4 months (which I refused because of cost), and now needs recharging constantly. If I was a heavy user or used this unit with others, it would require charging after every use. In conclusion, Storz & Bickel might be a great company or they might be like Volkswagen, claiming greatness without providing it. Check out user feedback on various websites and you will see the number of complaints about batteries, temperature control, overheating, and customer service. Oh yeah, and the cleaning videos are a joke, the cooling units require much more than wiping with q-tips and alcohol to clean them. Sorry if I ruffled any feathers here, but the Mighty and Crafty are highly over-rated vaporizers.
the adapters are pretty cheap
