I have had 3 of these now, I gave 1 to my sister and kept 2. Out of these 3 I noticed 1 has extremely small holes in the bubbler. It still functions but I have to clean this one with Iso more often than the other. I keep my reclaim for edibles btw. This is Chinese glass so if your holes are so small that it doesn't hit at all I would hope G9 would send you out a new one? I know my sister already dropped hers but luckily it didn't break. We should check the price of replacement glass from them too, I wouldn't mind having a spare. I'm sure shipping is more than the bubbler itself.
2 cycles is too hot even on your fist dab. I did notice that if you hit it with the nail too hot it is not efficient. That Ti nail is very thin so it goes from low temp to too high pretty quickly and you will notice A LOT more reclaim if you hit it too hot. If it's your first dab, go 1 heat cycle and dab when it just turns green. Any little bit left un-sublimated will vape on the next cycle. After the nail is hot and you have been dabbing a few I find it almost better to apply your concentrate to the warm nail it before pressing the button, then cap it press the button and start hitting. If you are dabbing several in a row you have to refine your tech a little but I found it works great dab style with 1 cycle as long as the nail isn't too hot, then switch to this pre-load method on my third. Just got finished using it with some GSC Full Melt bubble. Delicious!
