If you are talking about the printed 2 dimensional decoys with the spring steel frame... Buy yourself a decent lunch and save your money. They are very compact, but I wouldn't bother with them. I had a pair of hens years ago and tried them in OK on a field edge. The wind was blowing about 8-10 MPH. Although I had the elastic band around the peg on the side of the stake to keep them from flapping in the breeze, they looked swung and flapped around like crazy. Being 2 dimensional (flat), from any angle it would have appeared the hen was there one second, then gone the next, back again, gone again...
DSD period.
