@Titties_and_WeedOne thing I can think of maybe you are packing in too much too tightly into the bowl? I know if I were to do that with my solo I can barely get any good draws.
I fill it with a half teaspoon measuring spoon, and lightly fill it with 3/4 of 1/2 tsp (I filled it, then emptied its contents into the measuring spoon). There is zero resistance hitting the Grasshopper, it's one of its great features, so I'm pretty sure it's not packed too tightly.
For comparison I only use about 1/4 tsp in my Solo.
So, with my Solo I use 1/4 tsp over 30 mins to peak at a 6ish, and I'm good for about 3 hrs.
With my Grasshoppers I use 3/4 of 1/2 tsp over 25-30 mins to peak around a 3 or 4, and am good for about an hour and a half.
So yeah, I'm using more for less in the Grasshopper, compared to the Solo.
I just want to be clear that I didn't come here to shit on this thing.
I backed it on IGG in November of 2013, pre-ordered a second, and got three friends to pre-order as well. I've been a positive supporter on reddit's sub for the vape while waiting through the delays up to release. I've really looked forward to its release, and was super-excited when usage and review videos started popping up.
When I got my orders I was dismayed with their performance and have been reaching out to the community and the manufacturer since, trying to find if I've got duds or if this is just how this thing works.
Hopper Labs says this is just how it works, so that's kind of where I'm at.
