I loved the HA too, but I stopped using mine for a few reasons. Mainly I stopped getting primarily mids and got KB on a regular basis, which costed a lot more so I switched to a log vape almost exclusively so i can use tiny loads, which sure you can in the HA, it just doesnt feel the same. The log usage style and also worked better for my needs. They're always on and ready to go, and the mouthpiece and bowl are one piece (stem) that is easily removed, even mid-session should you need to, which was my one griped about the HA, once i dropped in the crucible and started I almost always wanted to vape until the end. While the amount that I loaded into a crucible on average was definitely enough to get be vaked a couple times, I would always end up too much of it up too fast, and I'm someone who likes to start with fresh herbs every time i vape, i have almost no interest in picking back up on a partially vaped bowl.
Another reason i stopped using it was because I stopped using it for one of the main reasons i got it - to revape herb from other vapes when i'm out of fresh bud. Sure, for a while there i was vaping the wdz abv in it now and then, but then I switched to QWISO for my abv, and i find that vaping QWISO goo is much more pleasant than any means of delivering 400F HA ABV vapor.
And lastly, the HA was a vape i bought to be used with my noob friends when they came by, and my gf at the time had started trying to hit my ssv but couldnt always get a good amount of vapor in the tiny puff that she would take, so i wanted to get a bag vape. Well she ended up getting preg and stopped partaking altogether, only tried the HA bags once. One friend really loved the HA but always got too stoned off it, to teh point he was almost lethargic, until one time he got so stoned he felt like he was sick i guess, when we did a packed crucible at 375F right off the bat lol. Another friend liked the HA straight up until the end but stopped having $ or herb to pitch in, so I would more often than not be offering up stems to share instead of the more extravagant loads of the HA. Either way, it just stopped getting used as a multi-person/party vape, which was the other main reason I got it.
So yeah, those are the reasons why I stopped using the HA as my primary vape. I eventually moved it and its accessories off my desk and to the closet because it wasnt being used and there was a change in my life where i couldnt just have tons of vaporizer stuff laying around everywhere. After spending so much time in the closet, i figured i might as well just sell it to someone that will get use out of it, and the money went towards buying a different log vape that was even better suited to my needs than the WDZ. If i had enough disposable income that I could afford to buy new vapes without having to sell ones that arent used much anymore, I definitely would have hung on to the HA, but alas, I am not rich.
But I would still say the HA is the best vape in some ways:
Best extraction for if you only want to vape w/o dealing with QWISO or cooking
Best vape for quickly getting a good effect off of not-so-good herb
Best party vape especially if you get the high-output pump and large bags or 3/5-way mouthpiece
Excellent lazy man/noob vape, no grinding needed, no risk of combustion even with having best extraction.
and thats why I still commonly recommend it to certain people.
