Actually, Rob is no longer making the original Mini which used the 14500 batteries, so the only way to get one of those is if they show up in the classifieds....which happens less and less all the time. The Mini he sells now is the Mini 2.1 version which uses an 18490 battery, just like the 18490 Woodvil. The Mini 2.1 is not quite as wide as the 18490 Woodvil. It would seem smaller in your hand for sure. They seem tiny to me. But awesome. You'd probably love it.
I have an all pink one and I have a white one with a pink door, just in case you want to keep the twin theme going.
