Meh...
I like hash. A lot. I don't sell hash. I keep it all for me. I like how hash tastes doing BT's will always be my favorite. I personally took about 4 BT's worth of hash and vaped it. I'm stoned.. but I'd say no better than when I smoke BT's.. and it made the smoke taste like vape...which I don't mind the burnt popcorn thing but I likely won't do it again..
Now that being said.. I wasn't asked my opinion, and I'm not challenging yours, or anyone else's.. I thought it was a brilliant idea to try for myself.. and offer my results up to see if others may want to try it and maybe give the OP another reason to buy it if he likes my opinion..If you are just looking for the stone.. It certainly is an easy way to brew your bottle tokes.. but it did totally change how it tastes to me.
My vape isn't "clean" right now either, and that may effect taste to a certain point.. but it certainly isn't dirty enough to totally change it to the extent that I didn't taste hash.
If that's cool with you, then there's another reason to check em out.
