Default Anyone Try the Muchbuy 3 Coil QI Charger?

Another qi charger. However, this charger is built with 3 coils instead of the standard 1 coil. This technology should negate the need for the phone to be placed on a "sweet spot" as seen with most other qi chargers. The only other charger I know of that has this technology is the TYLT VU which is a universally admired qi charger, but pretty expensive. Has anyone purchased this charger?
