I took a look at the Frankenskull you guys are salivating over and other than being a delrin BF
device, nothing special about it at all. In fact, I'm surprised no one has mentioned the fact they are using the square soy bottles that quite a few people have used in their Reo Mini 2.1's. The jury came back on those real quick as a very high percentage blew the side seam out of them and filled the inside of their
device with liquid... Interesting they would be using these since they have been used and rejected by the BF community!! There are a couple people that still use them and put up with the failure and leaking, but most have abandoned them for what they are.
