The Impcognito has been my daily driver over the last few months and I have really enjoyed it. It's my first 510 and first on demand/convection vape. I have owned other portables that were some mix of conduction and convection, but mostly conduction. I am using a Pico mod with Artic Fox. I also have VTC Mini with Tubo, but haven't used it. I like the compact size of the Pico and got the setting dialed in fairly quickly.
I use the wood dosing stem with the capsules and it makes it very portable and convenient. I started out with the Mist Vape capsules, but found that the Planet of the Vapes One/Healthy Rips dosing capsules fit perfectly in the stem without the bit that sticks out on the Mist Vape capsules. The POTV One/Health Rips allows the wood stem to seat completely unlike the Mist Vape stems.
I also use the Dynavap Fat Mouthpiece on the end of the wood stem. It seems cools the vapor and provides a bigger area to seat your lips. I find that I don't get the hot vapor on my lips if I didn't get a good purchase on the naked wood mouthpiece.
It all fits in a Pelican 1010 Micro case. It does a great job of reducing smell, at least to a human nose. The VTC Mini will not fit in the Pelican, which is another reason I don't use it. The picture is from before switching to the POTV One/Healthy Rips caps, but it's basically the same.
