I returned my DD today because of the exact same issues some posters are experiencing. Swing path is straight but the clubface is closed anywhere from 10-30 degrees, with all clubs. I thought maybe I was lining up the device improperly so I manually grabbed the club and swung straight across slowly with an open clubface, it still reads closed. The device is giving me 30-100 yard hooks for all shots. They have the proper distance readings but it's not playable with that hook. I configured the DD with all the stats from my Burner 09s, with the exception of the offset (as discussed before the max value on the DD is 1 and all my clubs have a higher offset according to the specs)

I guess its back to the Dome for me this winter. thanks for your help guys.
