Call me old fashioned, but I wanted an EVSE that was made in the US with US parts. Personally, I think they are more reliable, or at least it's easier to discuss warranty issues should an issue arise. The two that fit the bill are ClipperCreek and JuiceBox. I went the the CC because it has a "wrap around" area for the cord, comes with a protective cover for the plug, and I bought a refurb from the factory for a significant discount. It is a lot larger than the JB and if you're looking for easier portability, I'd take a strong look at the JB. Both have equal quality and warranty IMO.
Edit: Connectivity to the internet was not important to me, but if it is to you, that may swing your decision one way or the other.
