Ok, I have the opportunity now to give some first impressions review on my omnivap and the vapcap OG
I'll start by saying this: I don't use flowers much. When I do, I do not use butane vapes for flowers. This will be no exception. I've spoken around these parts about my rigid intolerance for accidental combustion and I have other vapes for flowers where I never run the risk of it. Of course, others can get good results with butane vapes and flowers for their needs and more power to them!
This is a concentrate based review.
The ceramic screen in the omnivap is not bad! Of course, I am not loading melty hashes and oils straight onto the ceramic screen (even thinking about that wasted goodness is upsetting!). For hash purposes I place an ss concentrate pad cut to size over the ceramic screen. I prefer the ceramic screen to the metal screen in the OG unit, I like that it stays put more than the metal screen when you are putting extra hash screens on top.
The adjustable airflow is really nice. The requirement to slightly twist as you pull/push the midsection over the o-rings kind of works against the turning to set your desired airflow, I find this twisting action to prevent messing up the o-rings can inadvertently mess up the airflow setting (but only slightly, and this can be compensated for with careful assembly). I really noticed the effectiveness of tighter draw resistance when I use the omnivap for direct draw hits. Prevents me from inhaling more than my lungs can fit (I'm used to rigs with the additional chamber capacity + my lungs).
The warm-up click is an irrelevancy where concentrates are concerned. You need to heat up about half as long again after you hear the click to get good hash vapor. However, the learning curve is less steep for concentrates vs flowers in the vapcap (and almost all butane vapes) - you just don't really have anything to combust in there!
The cool-down click must still be respected for concentrates IMO. I do not go beyond my initial warm up (1.5 clicks or so if that makes sense) without a cooldown click in-between hits. For this reason, this would not be the ideal vape for large groups IMO vs a desktop plug in for example. On the plus side, great for small groups with the benefit of your buddies not being able to break it!
I truly love the size of the bowl in the dynavap vapes. That narrow diameter is ideal for hash use. Also makes other concentrate use much more efficient than other butane vapes I've used. It is much easier to get an espresso tek style pack in this kind of bowl for concentrates and get an effective heat distribution through your material.
Now to taste. This tastes good. It won't beat out an evo on taste of course, but of the butane vapes I've used, this is as good as any other. Reminds me a lot of the vapman - the flavor is spent in the earlier hits. However, unlike the vapman, you do get meaningful clouds from concentrates while there is still plenty of taste. Flavor with concentrates seems to last longer into the bowl with the vapcap.
The only thing I could think of at this stage that would be much coveted for this herbivore in the dynavap range would be a concentrate pad (something like the S&B or Firefly 2 use, an SS coil that can sit on top of the ceramic screen to prevent gunk from melting all through the airpath while you warm up concentrates).
@VapCap if you make these, you will have successfully turned the vapcap into a concentrate compatible unit. I know we have the pyrovap, but this seems like it is not going to be the right tool for melty hashes and some of the other more solid concentrates.
As the OG Vapcap is quite similar to the omnivap, I won't spend too much discussing it separately here. I'll take a moment to say I also like the screen in this unit too and see how it would be nicer for use with flowers. The all glass unit is nice to watch vapor through, and tastes slightly nicer than the omnivap (this is not a very noticeable difference).
I can see how the glass at the outer edge at the end of the bowl could get chipped over prolonged use with excessive heating too close to the glass end of the cap, sloppy attachment of the cap over the bowl or rough use of metal tools loading the OG bowl. To me, the omnivap provides a piece of mind in these regards that justifies the price premium.
All in all, this is a great vaporizer and in my view, one of the best that I've used for hash and I'm sure it'll be my daily driver for those hashes that don't quite melt enough to be dabbed.
A very satisfied customer right here - I can see what all the fuss was about!
Phew!
