I use a mix of glass and straight hits. Temp setting 4 for straight hits and 5 with glass, usually around 3-4 hits per sesh. If I really try I can kill a fully packed load in one hit but my lungs just can't take it.
I'd say I get abut 2 1/2 loads per batt with a half full bowl. I'm more of a sipper than a ripper.
That's the great thing about the Grasshoppper, it's very versatile. Since I have two now, I mostly use the grasshopper the way it was "optimally" designed to be used which is a personal device for 4-5 very flavor full hits with just a pinch of material.
In a group setting at home, I still pack enough for one person and wether it's straight or through water, everyone finishes their bowl at their pace and then passes the Grasshopper to the next person to load for themselves.
This way people can use the strain of their choice, have as much or little as they want and get delicious fresh tasting hits.
On rare occasion where I really can't reload it for awhile, like at the State Capitol (not because you're not allowed to have cannabis at the Capitol, this is Colorado after all, it's just those jars smell strong when you open them, where the Grasshopper, once loaded doesn't smell, in this sort of circumstance I use it for like of a better way to describe it "o-pen style" (Bad references since o-pen just got busted for pesticides) which is to say, I load it up pretty backed (which I in general don't recommend because airflow is inverse proportional to pack).
So I load it very tight and full, and at temps 2-3 you can get great taste and effect without clouds, the height of discretion. Taking a maintenance hit like that, the bowl will usually get me through a full afternoon of hearings.
That said, I don't think the GH is optimal used that way so if someone is looking for a good starting point, I'd say, fill it no more than half way with fluffy or hand ground cannabis with a draw speed that if 10 is FAST and 1 is very slow, around 4 or so and a long draw. Anywhere temp 3 or above, I think it's hard to find a vape with that much flavor and that big of a cloud, and impossible to find one that can deliver that in 5 seconds.
I just had the Elo vape arrive yesterday. I will wait on my judgement of it but what I can say so far is that the 5 second startup time on the GH really is the killer feature when on the go. The Elo is yet another vape that by the time it's ready, (which is faster than Crafty or Pax2) you can literally load an empty grasshopper and take a few hits. I know this because now this is the first test I do on new vapes.
I also realize I inadvertently made my judgement on Elo, mivape, which is to say, for all its learning curve and that I didn't even use it anymore, I loved the Firefly right away, same with the Grasshopper. I like the mivape but again rarely use it when the Grasshoppper is right there!
Borrowing my used car salesman knowledge again, I think the reason the Grasshopper is going to do well in the market is the same reason that from a sales perspective, the best used cars are actually Saabs. Are Saabs unreliable pieces of garbage made by a company that no longer exists? Sure! BUT HAVE YOU DRIVEN ONE!
Unlike Toyota, Honda etc buyers, who shop around forever and are indecisive and always make the mistake of caring about price over condition which on margin (let's say you had to put in a new transmission for $2,000, there shouldn't be a $2,000 swing between comparable cars unless there is a REASON, and that reason doesn't bode well for the cheaper one) is far less important in practice and cost the mechanical condition, Saab buyers (granted they're also more informed) are great to deal with because either they LOVE the one you have and buy it, or the LOVE someone else's and buy it. They don't spend weeks comparing because since Saabs have actual personality, a person can actually make a choice.
Sure everyone wants a device that never breaks, for those like me who would rather be stuck on the side of th road in a Saab with the top down, trying to master the Firefly technique than driving the speed limit in a Corrolla sipping a Pax, then the Grasshopper is the way to go.
Alternatively if you want fast shipping get an Elo, reliability Pax2. In my experience those vapes deliver on those features.
