I might, actually, though I also have 4, if Sigelei hadn't changed the battery door from the cool open-book to that tedious door that comes completely off. Those are terrible if you're a klutz who sometimes drops her mod, the battery door goes flying, and only if you're lucky does the battery not come loose, not good at all for batteries to go flying like that.

The rounded back is the door secured with magnets. The battery is quite snug and easy to get out, at least for me. I use my thumb and curl my index finger a bit and it pries out, no problem. No battery chipping, either.
I have so many mods - and another dozen coming. But for some reason this is has been my all time favorite. It comes with the silicone sleeve which I love when around the house. I also use my Sigelei 213 with the sleeve. My colored Sigs are for when I go out. Like you, I like to be Mod Coordinated.
(Thank you for the list, Pami. )
