VapeXhale CS is awesome.
They sent me my replacement hydratube, which was actually an almost identical piece to the one I had. That meant it wasn't going to work with my vapexnails in any case.
But! They sent me a two pack of the quartz VXNs, which I was pleasantly surprised to find work very well with current HT. I went through a lot more of my wax last night than I should have, but oh well. I do agree with those who say they like using their EVO for buds more than concentrates.
The bud experience is flawless. I don't like how much residue is left over from my concentrate at the highest heat setting on the EVO, though that might be because my concentrate isnt top quality. Still, its decent concentrate, and I find that my first pull on a dab is usually tasty vapor, but then there is usually enough vapor for another pull and those subsequent pulls taste tainted by the burnt flavor of the residue that's still slowly burning off.
Still gets me very stoned off of just a hit, or two if im doing small dabs, but I prefer my friends traditional rig just cause it's more consistent and I feel like it tastes better.
Edit: Can a company rep chime in on how long it is safe to keep the EVO running for? I saw that they warn against keeping it on 24 hours a day, as that can cause damage to the heater, but I want to know how long is safe to keep it running.
I usually turn it off after about 30 minutes if I'm only hitting it every 10 minutes or so.
