Ive had the time to use this thing for about a week now and I can safely come to a conclusion on this thing(mind you your experience may vary depending on the wax concentrate you use). But my review will mainly be on the functionality of the device.
So for overall convenience and price; 8/10
Pros: Gets the job done, Useable dabs in seconds, easy to charge and transport
Cons: Little cloud vapor
Overall, its only $20 and if youre not willing to throw the cash out for a whole dab rig this will still 100% get the job done, althought it's probably wise you save up for a better rig.
