King KWM-1000 wifi booster

I just got a sample of a King KWM-1000 repeater. It's touted as a wifi booster, but to me it looks like a plain wireless router rebadged as a wifi booster.

Anyone know anything about this unit? I have not had it apart yet to see what it may be made of.

This site has some nice info:
Looks like a Realtek chipset is being used. The 2.4 GHz chip is unreadable but the 5 GHz chip has RTL8812BRH written on it.
