I've been having what seems to be a fairly common problem. When I tried vape mine & my husband'a SVD isn't working. When I press the first button I will get the reading "0.0R" & the first button turns red for 5 seconds. Tried this will different thanks same result. Help me please! Oh & I've checked the grommet it's fine & 100% intact.
