I will start by mentioning the biggest downside for most people insterested in this product - you cant get big hits without making a mess inside the pen. If you're expecting to take huge hits with alot of wax like you would a rig, then this isnt for you. If you put a ton of wax and take a big draw, it will shoot up a lot of the wax clogging the screen right below the mouth tip, itll get wax all around the green plastic tube, and around the threads that keeps the parts in place. I'm not saying dont get this pen, however I just want to make it clear that if you only plan to chief down big hits with this pen then you should probably look elsewhere.
Otherwise, this product is phenomenal for me. I've put all types of wax in and used this with no issue. As long as you put a mild to medium amount of wax, you can hold the button down until it times out for a nice long draw that brings a lot of vapor for a great hit. Smooth and non-harsh hit as you're not getting the heat like you would out of a lot of dab rigs, which is a big plus and the main reason why I purchased this. The first day I wasnt getting a lot of vapor and concluded it was due to me breathing in too slow with not a lot of force, at least in comparison to other wax pens I used that would take barely any effort to inhale the vapors, so just FYI in case you watched review videos like I did and then wondered why you cant take a nice hit like the reviewers were. Just test your efforts is all I'm saying, you'll quickly find out how to get it right.
Battery lasts a long time, this looks sleek and discreet, and has a 510 thread so you can use vape cartridges as well. Very portable and great for on the go use.
