Actually, thinking about it, there is one thing that I definitely don't like about the Cylon vs the Battlestar. The battery door opening at the bottom. I don't have a problem with the construction of it (I think some review, possibly beta, models had a problem with it flipping open too easily), albeit it is a bit flimsy for my liking, but it's a pain that you have to take some attys off to avoid juice spilling out just to change the batteries, on the Battlestar it was easier, flip the back panel off and change, no need to think have I drained this RDA enough or does this RTA leak. Thankfully you don't have to do it too often, and I guess there's less of a problem with a hinge / clip mechanism vs magnets over time, still not keen though.
