Hey all! I've been interested in the bathmate for a long time; it looks fairly effective and I love the idea of increased flaccid hang. I've got some extra cash right now and was thinking about buying one, but I'm not sure where to buy it! There are tons of different options online and I don't want to end up with a knockoff. Also, sizing question: I'm between 6.5 and 7 long and 6 in girth. Which model should I get? I worry that the 7-series won't leave me room to grow but that the 9-series will be too large. Any advice? Thanks!
