I have two of these things. Scratch that, I have one. Here's the story.
I bought a Standard canada goose unit and a ultralight duck unit. I got both of them at the begining of last year.
I thought they looked awesome like you, and they do when they are up in the air, but that's the problem. I tried the goose unit several times during field hunts, and only took it out during windy days. The thing needs a crap ton of wind to stay aloft. The longest I ever seen it stay up was 10 minutes, you end up running back out into the field every ten minutes to throw the thing back up into the air. Needless to say during one of the last hunts we had I had enough and shot the crap out of it when it hit the ground seconds after putting it back up.. SO ya i blew it all to hell.
Moral of the story is, try the ultralights if your going to try them at all, I haven't even tried my duck unit because I usually hunt ducks over water and the reel wings is tough to use over water, so I use the Mojo's.
I will say when it was in the air, ducks really reacted to the goose unit, almost landed on it. It for sure catches their attention.
Just don't let if turn you into the guy jumping in and out of your blind to use the thing. It gets old fast.
This year I'm going to try more jerk string's and some other way to motion in the field spread, which I haven't finalized how yet. Thats why I'm here. And as much as the mechanical battery powered wing flapper goose decoys look. The last thing I need is more mechanical battery operated crap to haul out into the field. Tough decisions ahead.
Good luck with your purchase of reel wings, and don't bother unless you are in a relatively windy part of the country.
