Honorable mention: if it had've come earlier in the year, the Vapvana Ace probably would've been in my top 3. It changed how I saw wireless ball vapes, and it's changed how I dab.
3rd place: I've had it nearly 6 months now, and the VerdaVap is still the first vape I reach for most days. Doesn't matter that it's unregulated, with a timer it's so easy to use, and it's such a powerful, but easy extraction.
2nd place: When I first started reading the promises, I thought "that's just a whole lot of nice sounding words that don't mean anything." Then the Vestratto Tornado turns up and everything you've read about it makes sense. I love this device, it's so powerful, it's such a different consistency of vapour. Just last week I got the stem adapter, and I'm using it even more now.
1st place: My favourite vape of the year is one that I tossed and turned over for months, cos the Flower Kettle + Electropath comes in at a price that you need to be really certain of! I've used it nearly every day since I've had it though. It's so versatile, I've had so much fun experimenting with it, and whether you're vaping some shitty tasting weed or the dankest of dank, there's a setting you can create that will optimise it/deaden flavour/change whether you sip or rip/be suited to different rigs. Also, double stacks through it rule hard.
