I have a Yocan Flick arriving very soon. What is that, you may ask? It is an improved Yocan Hive in that it has exactly the same functions, except the Flick has a flip-top cover that protects the mouthpiece/product insert much like a Zippo lighter flip-top protects the flint wheel and wick from pocket waste. With the Flick there is no need to remove pocket fluff from the mechanism prior to taking a well deserved rip. It's a clean machine. See it here. Like the Hive, the Yocan Flick is about 3.25 inches long (81mm), but is wider: 2.6 inches (67mm). Like the Hive, the Flick has two magnetic cartridge inserts for quick change: one for oil and one for concentrate. The magnets can be removed, and the inserts can be used on any 510 threaded device in a pinch. I am not sure if the Flick has temperature control like the Hive 2.0. That is very important for me. I prefer variable control, so that I may find that temperature sweet spot for me. I'll let you know how it works out.
