Using one of these the right way has produced one of the strongest highs I've ever felt. I tweaked hard. But much more often, it was either hard to get even a buzz, or it ended up burning some bud. So I believe people when they say they love theirs, but they must really know how to use it.
It worked, but did end up burning a lot of bud in my experience. Also mine gave up the ghost after like 3 months. I can't remember how much it cost, but it was pricey for a college kid
It was hyped up because of astroturfing on Reddit that got the r/trees mods banned for being paid off. That's also most likely what's happening right here.
Pretty sure this was the first one I was exposed to.
High school, friends parents out of town, out in my buddies shitty '95 hatchback civic, they pull this friggin thing out. I was so impressed, good memories!
I used mine a couple years ago, still works... as expected :) I did give up on batteries tho and picked up a power adapter, which makes it a much more functional device.
