After buying a Yocan UNI Pro, I want to confirm with you and do you use it correctly?

Tips 1: start around 2.2v, 2.6 for live resin
Tips 2: preheat twice if your material is very thick
Tips 3: clean your cartridge's bottom and touch-points regularly
Tips 4: Make sure the magnetic adaptor is screwed into the bottom of the cart
Tips 5: try to Vape from lower voltage and change to upper voltage setting later

Any more tips? Welcome to give your comment!
