Well said TinaF1971, agree with that...I love my Spinners, they are nice, fantastic quality, but the device offerings are a tad thin on the website and SI doesn't seem to be blazing forth real speedily with new product announcements. Take the CE4's they sell. I'm sure they're fine and work well, but they are NOT rebuildable...so I looked and bought a pack of Vision 808 rebuildable CE4's from another vendor. I've kicked around buying a couple 510 eGo's, but decided not to, the Volts are good, got enough batteries, don't want to spend, more to keep and maintain, so I picked up the 2 adapters - 808/eGo 510 and the regular 808/510. Now I know I can throw anything out there on top, no matter what SI does/doesn't sell. I've noticed some people seem averse to using adapters, I'm not, that's what they're for. I don't keep that many different devices (don't want a lot!) but for what I use when an adapter is needed my setups look fine, nothing a thread sleeve won't help pretty up!
