Is there fully working mpcie to m.2 sata adapter for Omnia SSD?

Mine is actually a cheap Chinese one (but bought it from Amazon, but you will find the very same design on aliexpress as well) - have a look here: Disk for the module B - #4 by ssdnvv
There are some reasons for not going with mSATA (Disk for the module B - #2 by ssdnvv).
