I did the same thing, ordered one BF-ERA and was sent a drip ERA. Luckily, I know the machinist at my college, and he bored a 1/16 hole through the bottom, and it seems to feed perfectly through the hole for the coil. I will admit, it is slightly disturbing to have not received what was ordered, but it can be made to work.
If you bought through the Indy Vapor Shop group buy, I have been in touch with Mike, and he basically said that he didn't open the packages and there is nothing that he can do.
