Plus Device

Battery itself is great, my ceramic chamber stopped working/connecting to the battery after a few months. Overall great device, maybe not for somebody looking for longevity unless you buy more chambers.

I can honestly say that this is one of the worst devices I have ever used. If you don't clean it after every use, it simply won't work. I just got the device and packed it twice and it's already not working. Seriously, save your money and go grab an Ooze Beacon pen, which works a lot better and you hardly have to clean it. Please, do not buy this device. They have spent all their effort on the outer design and aesthetics and completely overlooked performance. This device is the most sensitive and annoying device I have ever used. I cannot caution prospective buyers against this device. Please consider the Ooze Beacon instead of this heaping piece of ass.

Product met my expectations and more. Love it. Would def recommend
