Anyone pick up the REVVL?

I've been thinking of going full cheap-o on my phone to save some money, and lo-and-behold here is the REVVL to save the day (maybe).

Just wondering who has picked on up and what their thoughts on it were. It seems pretty legit on paper for the price.

I've narrowed it down to either the REVVL or the LG K20 Plus.
