Does anyone use these cables for their SATA drives?

I bought a couple from Monarch and they are much better then the standard SATA power and data cable connections at staying on. They are indeed secure, and as they combine the power and the data cable into just one cable, there is one less cable to manage.
There is just one problem that I've found, they do not work! I've tried two different cables with four different drives that work with the normal SATA cables, and the mobo cannot detect the drives with this cable. Anyone have any luck with these?
