Owlet Dream Sock

Unused Owlet Dream Sock. Going to be transparent, my owlet smart sock 3’s sensor broke and my daughter was sick so I was in a rush to purchase something as fast as possible. So I purchased this unused Dream Sock on Poshmark. Once it arrived, I realized it was a dream sock(the newer one) and not a smart sock(older one) and it wouldn’t work on my old app(the one I prefer) so I went through owlet instead and purchased a new sensor. Now I have two perfectly working owlets but don’t need both, so just trying to get my money back on this one. I’ve looked over every inch and it’s in perfect condition and comes with the box!
