Well I'm on day three/four with the hopper (things have gotten a bit blurry
). I wanted to write up a more in-depth review, but I feel that most of the things that I would have said have been covered by other hopper owners. I've had a very positive experience so far! I haven't really measured battery life and would be mainly speculating, so I'll pass on going in to more detail in that area for now. I'll just say that with four batteries total and a D4 charger, I'm not too worried.
I would say there is a small learning curve in regards to optimal use for the individual or group using the hopper. This is mainly load size and how you want to surf temps. I've found that anywhere from a medium-light to medium-full pack (relative to bowl size) gives me the desired results. I personally prefer to start at 3 o'clock on the temp dial and turn it up as I see fit throughout the session to around 4.5 o'clock max. I'll set it to 5 o'clock on the temp dial occasionally, but I usually don't need it that hot because I don't prefer my material quite as spent.
I have repurposed a traditional oil pen case for use with my hopper and it is perfect for my use! I can fit the hopper, a small brush, 4 batteries (one inside of the hopper itself), the silicone mouthpiece, a doob tube or two, and the Crafty/Mighty CU with the FW 3.0 mouthpiece. Additionally or alternatively, I can carry a MFLB glass mouthpiece in there for use for vapor/mouthpiece cooling as well. I have found both of these cooling methods nice and useful, but definitely not necessary. That being said, I would have to agree with the sentiment that this is not really a session vape in my opinion. I feel that it could be used that way, but this things really shines for getting a monster rip or two and then "set and forget" until the next time I desire a pull or two. The effects from this are awesome, so it usually at least a little bit until I am reaching for it again.
Here I am ranting again
