Tanks don't work well with tread adapters

[LarryPer]

Quick question
New to vaping
I have a Lambo and a adapter to use a Karger T3

I seem to get a lot of air and dry hits
Could it be the adapter?
Also have the same trouble with another brand---different adapter

I use the T3 on a smokeless Image brand and no problem
Could it be the converters causing this or did I just get a bad T3 ?
I tried different voltages and same problem


Thanks Larry
