Hey guys. I was wondering if you guys knew where I could get the little (disposable I guess, not rba) dripping attys that have none of the filler material. Basically just looks like a little tube with a coil on the inside, 510 connection. I bought one a few months ago but it was leaking bad and the vendor didn't reply to the email I had sent regarding the issue, so was looking to find a different vendor. Thanks in advance.
