As a long time buyer of vaporizers I bought the Fog pro on the basis of the performance of the Xmax Starry 3 which I find to be an excellent device. On reading posts here I got the impression the Fog pro was similarly good. One of the Starry's strong points is its generous bowl. Going by posts here inferring the Fog's oven is also on the generous side, I purchased one and find that it only takes ~ .2g. It's my first vape with convection heating and I don't like it one bit. I started it at 390f the same as I use on the starry. I set it to a 10 min session and waited a minute or two (even after the haptic vibration, which I'm not fond of) and took 6 second sips with 30 second gaps between and found there was next to no visible vapour unless I sucked and then blew when vapour clearly issued from the cooling grills. I did this because I wondered if there was an air leak on the head unit or around the mouthpiece swivel. Anyhow there must have been something invisible coming through as after the sesh I could feel about half the effect I'd get with a similar sesh on the starry.
On emptying out the bowl the top layer of grind was just as it looked when loaded. I could see the layers below had a certain amount of browning, but not like one might expect, they certainly weren't spent - a mid even brown, top to bottom and side to side as I see in the starry or other vapes.
In subsequent sessions I raised the temp to 415f on one and then 425f on another and not much better at extracting cannabinoid at those levels either, but It has irritated my upper respiratory system and that's something I avoid like the plague.
Either the convection system doesn't suit my needs, the Fog pro is faulty or it's just a crap device.
I've now ordered an Xmax Ace which has similar external dimensions to the Fog pro but has conduction heating. I don't think the Ace will have a bowl capable of taking ~ .3g of grind like the starry either. Why don't the producers of vapes give this info?
My verdict on the Fog pro, is unless you know it's for you - a friend has one for example, don't buy it.
Hiya, I had similar frustrations to you with my fog pro, I've had to do a lot of experimenting to work out what's going on in there. I found that the fog is a good device, but the V3 Pro seems better. The fog has a few flaws that affect ease of use and function, the obvious being the swivel mouthpiece, although replaceable, annoying to worry about.. weakish top magnets, a little cumbersome to clean, though good relatively for convection.
Function flaws would be that it seems the vape is targeted to people that enjoy the vapor taste itself and use often. In order to improve this experience they wanted to increase the bowel size not just for more draws, but even less conduction and more convection for taste combined with cooler vapor from a longer path makes it the best and most comfortable vape for its target consumer. One good side effect is the abv can be more even cooked than perhaps the V3 I'm assuming if you mix the bowel halfway (perhaps twice mixed). The problem is in order to achieve even heating while also producing the maximum amount of vapor requires other variables to vaping to be more specific or consequences are more dramatic.
Firstly the more herb in the bowel, then the more heat distributes in the bowel for more intense vapor release as its heated all together. Secondly, the herb needs to be relatively fluffy, but not too fluffy or there's too many air paths throughout which doesn't heat some of the herb (If too dense then it burns at the bottom more). There's other consequences to making the bowel bigger with the traditional oven (only holes on bottom) and that is more time to heat up the herb (noticeable even between draws).
So the main technique with the fog pro is to prime the oven slowly and then increase draw speed to a more comfortable rate, but still slow relative to other vapes as you're relying on the convection in there to move around evenly while you're drawing for consistently high vapor. Unfortunately all this leads to a draw average time of about 20s if you want harder hits. It won't beat the V3 in hitting you harder because with the V3 you can draw faster even if the total vapor per breath is much less, you probably get more vapor than the fog in 8s then you would on the fog in 12s as an example.
After you mix the abv around once vapor is dropping off, you can then increase temps. I personally start with 185C before the first stir/mix, but if its cold air then I increase it in combination with slower draw (this goes for all convection vapes).
Lastly if bowel is packed less then it needs to be packed a bit more with a bit lower temp and slower draw to avoid the herb flying around in there producing an air path of that doesn't cook pretty much most of it and it'll gunk up the filter piece faster.
Anyone with a V3 Pro and Fog Pro care to share their input?

I use the Ace mp top now because the magnets are way stronger.
