vacuum device doesn't work...frustrated
I just received this from Amazon
The stone will get sucked into the end of the device tube but will not pull it off, the stone comes back out of the tube when I pull. It is not as big as some being posted here. The stone seems to be encased in a sac or membrane so it is stuck to the mouth tissue pretty good. Is that normal? It looks smooth, not like the random nuggets I am seeing in these posts here. I even tried to soften the sac with vinegar beforehand. I wanted to post a photo but my tongue looks nasty, I am a smoker.
