I've put off buying an Arizer product for a long time because I couldn't wrap my head around its bulky design and having to use a glass stem for a bowl but quite honestly I'm pretty surprised. Its not large at all and comparable to my other vaporizers. The glass stem bowl is actually a real selling point for me because unlike other vapes where you must load ground material directly into the oven the Solo II requires you to load material into the base of the stem. This translates into zero airpath blockage provided you use at least a medium grind. Battery life is very respectable although not the stated 3 hour duration. I suppose if you vape lower than 190c on a regular basis battery life may improve. The device is super easy to use, easy to clean and the handy protective tubes that come for the glass stems is a nice touch. You can get some fat clouds out of the Solo II so I recommend getting a glass bubbler to go with it to cut down on the irritation. The hybrid oven combined with the glass elements really go above and beyond to accentuate flavor. My only gripe is the little baggie the factory sends with the Solo II does not permit the storage of the glass stems inside their plastic tubes and the screens are too tightly woven. Why store your loaded, exposed stems during storage with a high risk of breakage.
