I've received my replacement unit from Linx. Very happy with the customer support. Unfortunately there a few things that annoy me about the new unit. The power button is extremely clicky and loud compared to the old one. And the draw resistance is greater, which is a drag since an easy draw is one of my most desired qualities in a vaporizer. Not sure why that would have changed from my old unit. Perhaps there is some variability in the air holes of the quartz chamber? So great service, vape works well, but I wish it had an easier draw like my first one.
