Pros: Looks like it might be fun

Cons: Doesn't end up being fun
Doesn't swim well, doesn't hold decent charge
Waste of helium

Other Thoughts: Bought this on sale, was waiting for my nephew's birthday (last week) to inflate and have fun with it.

That didn't happen. While it was easy to assemble, fill and charge, the thing would simply not swim properly. The 'ballast' pod that raises or lowers the nose attitude would jam on the string, despite adjusting the tension several times. It was as if the pulley inside the sealed pod was not working....so the bird just floats to the ceiling, and does circles up there. No up or down, no real anything but sideways circles on the ceiling (reminded me of a dying goldfish).

Battery didn't hold much of a charge - had recharged twice, and the tail motor simply started cutting out after about 20 minutes of trying to get the thing to work properly.

In the end, the kids better enjoyed the regular balloons that I filled with the remaining helium I had from the canister I had bought.

The only angry bird to mention here is the gesture I gave this thing.

FAIL.

Pros: Price, easy installation, nice HD picture reproduction and viewing angles (despite my problems below)

Cons: Ripples and 'memory lines' across screen surface that did not go away after 4 weeks, had to RMA with manufacturer.

Other Thoughts: According to Elite Screens tech support (very nice, btw), the ripples & memory lines are usually caused by screen sitting rolled up in a warehouse for too long, and/or improperly stored.
Waited 4 weeks for ripples & lines to diminish, when they didn't, I sent Elite some pics, and they determined that the screen was in pretty bad shape and warranted replacement.
I opted to RMA with Elite rather than NewEgg, figured hopefully less chance of a repeat problem if the replacement is a bit more 'fresh' from the manufacturer. Still waiting for replacement.

FYI, if you do have to get RMA service from Elite, they only ask you to send a 24" square of the screen, plus the end caps...beats the hassle (and cost) of sending back the entire thing.
