Just a question which I know some of you can answer - what size/gauge & material are the DaVinci Ascent screens? If I buy a sheet of mosquito netting (metal? steel?) and cut it up - will that work? UNRELATED EDIT: I've been looking at backups for the Ascent. Was sold on the Flowermate 5.0S mini but my grow store doesn't stock them. I came very close to buying an Air, but then I saw the Xvape Vital - for 70€. and took a chance on it (after a quick Internet search, - no great reviews but no shockers either) and was very impressed straight out of the box. The only other Vape I've ever used is the Ascent with the ceramic chamber and glass stems so I wasn't expecting a cool session with this one - the chamber is very close to the mouthpiece and the mouthpiece is hard plastic. But the chamber is ceramic, easy to load and @ 195°C (383°F) it didn't seem harsh at all. I think this is partly due to the air vents surrounding the chamber - the draw is easy and smooth, basically just breathing in. I see there are glass stems and a dinky water attachment available as accessories but I doubt I'll get those. The Vital is super stealthy, fits in the palm of the hand and could be mistaken for an asthma inhaler (but stylish). The airpath is separate from the electrics so no worries there. It has a non-removable battery and charges via usb port. It wasn't the Vape I set out to buy but for 70 bucks I think it'll be a fine secondary Vape.
