The Cabelas closest to me has all their lanterns hanging above the "light racks" and I pulled them all down one at a time to look at and compare them to the ROV 3D LED lantern I have at home. None of the lanterns they had there matched in my opinion what the Rayovac Extreme lantern offers by way of brightness and usefulness.
The 12 LED lantern itself is built well enough but even at the $20 sale price, I'd rather have my Rayovac 3D lantern for ~$10 more. The ROV is much brighter than this lantern and those like it.
The 12 LED lantern I looked at also has a remote control, it's a nice feature but it will also drain your batteries while in storage. The functionality that makes the remote work needs to have a constant power source applied in order to turn the light on when the remote is used. I think this would apply to all lanterns with such functionality. The power draw is likely minimal but the lantern draws this extra power whether the light is on or off.
To be fair, the ROV does have a blinking beacon light which can drain the batteries too while in storage.
