Pros: Small size. removable battery.

Cons: Could not use it because Newegg shipped model that only works with Sprint modems. Newegg product description stated model PHS300. Cradlepoint website lists my 3G modem (VirginMobile Novatel MC760) as a supported modem. I could establish WiFi connection with PHS300 setup pages but there was no internet access. When I tried to access internet I got an error saying I was using an unsupported device. Talked to Cradlepoint and they had me check model # in battery compartment. It was actually a PHS300S rather than a PHS300. The PHS300S works only with Sprint modems. Newegg shipped a model different that what was ordered. The PHS300S is not listed as a Newegg item so I am not sure why I received one. Cradlepoint tech support was very helpful.
