I'm finding 1 hit at level 1, then 2 hits at level 2, and all three of them are nice and cloudy. My ABV is nice and dark brown (at least as dark as I like it)
Really complete extraction, I would say quite similar actually to an IO, with slightly different signatures.
The heaters seem actually very comparable to me, but there are some differences. I think the Hopper IO has slightly more conduction occurring in the longer metal chamber, and the vapor just seems hotter accordingly. The difference after the heater is that the IO really has no cooling, so really needs supplemental cooling of some sort (at least a short extension), and is best through water, whereas the Tafee has a complex enough path with heat sinks involved in cooling the vapour, so no additional cooling required.
Both designs have their merit in my opinion and both are excellent devices; both devices heaters are great and really shine as far as being able to produce consistent results at different draw speeds.
I haven't opened up my Tafee (and don't plan to any time soon as I don't plan on voiding my warranty), however, I doubt the Tafee has a proprietary battery. The IO on the other hand, although the battery is proprietary, it is replaceable which is a plus.
(Didn't plan on this being a Tafee vs IO review, however, find myself considering how similar but different both vapes are)
Actually ... I know I'm rambling here, but the 3 vapes I have in rotation right now for flower are the Tafee, Hopper IO, and the Neo. All 3 are unique and really compliment each other nicely.
- The IO is that super heavy hitter through water, that's also great with a small drip-tip when portability is required
- The Tafee is just really nice to just sit there and chill with, and it hits like a tank as well
- The Neo is just great when paired with the right glass bowl, and really has great flavour with a j-hook. It's not convenient or as hands-off as the Tafee though, it requires more user involvement, and more technique to get great hits (although with just a little practice, and the right bowl, the Neo hits hard too).
As far as efficiency goes, I feel the Tafee and the IO are most efficient by a wide enough margin, but maybe that's because I'm not a big fan of stirring ... the IO and the Tafee really do not require any stirring at all, whereas the Neo does to not waste some.
