Thanks for all the answers, OF! but now I have another quesion.... Earlier you told me: and ogcook told me: . .Well I just got an email back from the people at ThermoVape and they completley disagree with you, so now I'm really confused.... all I want is a functioning DART! is that too much too ask? haha, well I guess I can use the window loader with my oil, it just turns to liquid when any heat is applied (like basically all BHO) so I hope the window load will work fine. Again, any comments on the glass adapter?? http://thermovape.force.com/IdaProductDetail?id=01t50000001qlFdAAI I really would prefer to smoke through a glass mouthpiece/bong than a rubber/plastic/metal tube.. Thanks again for all the help and great advice guys! PS. guess it really doesn't matter now anyways, when I tried to order the DART top from thermoVape it told me they no longer have the item. I sure hope the side window loading Rev works just fine too because it already cost me twice as much as the eGo batteries I'm putting it on. I know it doesn't sound like much but the over $100 I've spent on this is the most I've spent on accessories in 10 years, I always get shitty glass pipes kicked down to me and had the same bong for 10 years then after it broke I was lucky enough to find a glass on glass bong in the room I just moved into (gotta love humboldt county, rent a room for $300 a month and find a $150 glass piece in it, score!) I usually either grow or get all my herb and concentrates for free because I'm not picky and don't have the money to buy anything, so I'm having a hard time justifying the $100 I just spent in the last 2 days but I hope it ends up paying for itself a few times over, I have a couple ounces of BHO so if this thing really can get me lots of hits off a few dabs that will be a great improvement over just dripping a ton over a bong bowl and making a sticky mess everywhere/losing a lot of BHO in the process..... Sorry to ramble, just excited/nervous about my new toy!
