Wow where do I start? I'm thrilled with my new ud twig.I have been pulling some hefty clouds since I opened the box. It has essentially replaced my mflb and forced it into an early retirement like state...One thing I was not expecting was the limited odor.That was the number one reason why I have shied away from a log vape. But i found that my mflb actually produces even more of a smell. Ive had no problem using and maintaining my twig.I usually get some herb in the heater element but tap it out.That would be my only concern,could I get buildup there? Im really diggin the wongs and want a bethlemen olive to give my wooden pinup(thats her name) a hat.Thanks for making such a top notch product Dave.
