Long time lurker.. thought I’d post my experiences with the Grasshopper as it differs a bit from the average post here. For context, I also have a Firefly 2, an Arizer Go, and some others— they generally work well and have different pluses and minuses. I have couple of Ti Hoppers. I am usually the only user, I don’t chase clouds, if anything I’m more of a micro doser and take a few hits through the evening.. perhaps 2 small bowls a day. The two hoppers are different vintages, one early one more recent. They both work great and I’ve had no issues. I have a few batteries I rotate and have always charged them externally. I keep the hoppers clean. At this point, it’s the only vape I use.. tastes great and is incredibly quick and discrete. They’re also great when out and about, one can take a quick hit without notice. I guess I’ve been lucky compared to many here, and I may not be pushing the units as hard as some. For my purposes, it’s hard to imagine a better setup.
