Hello there,
bad update: I broke my second Glass VG
....sad accident... jeez, I have bad luck with this pipe... But it's not dead yet. Luckily, the pipe can be held by rubber bands, and works well with good seal....also better access to the residue on the other hand
what is worse, recently my top piece has broken as well, which made the GVG useless (altough I managed to vape only with ceramic sponge isolated with another screen, but didnt work well because the filter alone is too small for that wide bowl) ...
other news: The ceramic filter is not as durable in a long-term as I though ...
since my top piece broke, I could play with the filter a little, and to my surprise, when gently scraped with tweezer, the filter leaves the black dust....this might lead to others' statements on VaporGenie thread about 'shrinking VG filter' which I also experienced. I am quite dissapointed due to this.
However, I contacted the vaporgenie chief and it seems they will not send me the Top piece of Glass VG even after I bought 3 Glass VGs and made a wholesale inquiry. I am quite pissed. But afterall its my fault. I consider to use GVG with some all glass filters like Clear Dome's flame filter of HDVape heat diffusor.
