I’m completely changing my original review. I decided to give this device a second chance and more time to experiment with it. Once you figure out what heat setting works best for you, this thing can hit! I also recently found myself having this stealthy tank as my only concentrate option on a trip and felt pretty grateful I’d gotten it. That’s really what made me change it to 5 stars. It’s an affordable and convenient concentrate tank that does exactly what it’s trying to do.

Let me start by saying the concentrate chamber is well made and definitely does the job its meant for. Now, I gave 3*s because there was absolutely nothing with it except for a few stickers for random companies and a paper telling me who the "picker" was. Not everyone who buys these products has used them or anything like it before. Instructions, a paper the size of a fortune cookie fortune with simple instructions would make more sense than nothing at all. Also, what is with the lines/cuts on the product? It makes it appear like there are multiple compartments to unscrew when it's really just the 1 at the bottom which wouldn't matter had there been instructions to specify if it was something to unscrew and clean or w/e. I have a Uni Pro and its a stuggle to get the magnetic ring attachment to connect to the chamber. As in I have to press the 2 items together as hard as I can as I turn one of them to get the adapter to thread so it can be used. If I don't do that, it appears the adapter is too big and the threads don't grab hold. I absolutely would recommend the product so far although I've only had it a couple days. Just if you're new to consuming concentrates in this manner, be prepared to be a little lost at first.
