Okay let's try this again...
Got my PUFFiT yesterday. I immediately fired it up without charging and my impressions are as follows. For perspective I also own an MFLB and an OG Iolite - though I've not used the Iolite in over a year. The MFLB is my daily driver. I've also owned several home vapes, and I'm a frequent visitor to some of the vapor lounges in Toronto, where I live.
I usually grind my herb very fine with a credit card grate grinder. I couldn't find it last night, so I just hand ground. My herb is fairly moist right now, and I just tamped it down with my pinkie finger. The following observations follow this method for all three bowls.
PUFFiT comes to temp very quickly. i set it to six/seven then turned it up to eight for the last two hits of each bowl. I don't take the first draw after it warms up, instead I let it cycle one additional time before inhaling, which reminded me of using the Iolite. Although vapor production was low, I was able to get visible vapor on almost every draw. Not billowy/cloudy vapor. Not as visible as the best on an MFLB, but definitely visible. YMMV depending on lighting conditions.
The roast seemed fairly consistent. All three bowls I vaped seemed to have the same uniform chocolate brown color. I generally like to vape my ABV a little lighter, for cooking or emergency smoking so I'll have to mess around with temperature.
As Coastal and mmenzie mentioned, it's very easy to over medicate. After two bowls (both combined were less than an average trench in MFLB), I felt severely medicated. More so than I've ever felt from the MFLB.
I find the plastic taste to be minimal. Yes, it is present, but after three bowls I do feel like it's dissapated slightly. Once I'm done this review I'll fire up another and see how it tastes. It could be because I'm medicating with Kush right now, which tends to be strongly flavoured anyways. I may try to vape some mint tea at temperature setting eight and see if that helps. As always YMMV. The taste didn't really bother me and it's definitely not the worst tasting vape - I'm looking at you Iolite.
The battery got me through nearly three full bowls UNCHARGED. I'll do some proper field testing today to see how it handles out in the community after a full charge. If PUFFiT can run through two full sessions, it should meet my needs nicely.
PUFFiT is undoubtedly the most stealthy vape I've ever used. Drawing from an MFLB or an Iolite still registers a few curious/suspicious glances when out in public. I imagine the same would be true for Davinci and Solo. I've jury rigged stealth solutions before, in fast food cups and using surgical tubing so I can hide the devices in my pocket... but PUFFiT's unique form factor makes it inherently more stealthy. I don't imagine average passersby will notice you are vaping. Yes, it's slightly bigger than a ventolin inhaler, but having used such inhalers in the past, I don't believe the general public will notice the difference.
Battery indicator is totally useless, as others have noted. Three clicks still showed green just seconds before the unit died on me.
(SEE EDIT BELOW) My cap seems pretty solid, not sure the issues others are having. I do find it easy to "screw" into the wrong position, which impedes the clicking motion. More experience using the device is likely needed. I do worry about losing the mouthpiece cap. Hopefully we will be able to order replacements soon. I'd stockpile a few as I tend to misplace small pieces like that.
I can't think of anything else right now.
The photo of the ABV looks very light due to the flash on my phone. To the naked eye it looks uniformly brown. The other photo has my MFLB and heavily used Iolite in it. Sorry for any blurring and clarity issues.
And before anyone asks, that's a bathtub in the background, not a toilet.
Questions are welcome, I'll do my best to answer.
edit: Almost right after posting this I noticed my silver top cap was missing! Thankfully it just rolled off the table I was charging my PUFFiT on. However I guess I was wrong about how solid the fit on the cap is.
Also, the unit gets VERY hot. It don't think it will burn, but after a few consecutive bowls it does get a little uncomfortable.
