I saw this today at the Houston Wal-Mart (Wayside). It was on clearance for $15. There were at least 6 (the clearance is at the far left of the store near the toy section). I checked brickseek and it shows it for $15 at the Wayside store but higher for other stores.
I don't know anything about it. Looks like laser tag. Cheap Christmas gift for family or donations? There's also a Homido Grab Virtual Reality Headset for Smartphones there for $7.
