I have bought two -522 ULF module and they work as advertised. My VZW Treo 650 and VZW RAZR pair up great with them. One is in a X5 and one is in a M3.

Also, xoutpost.com does have EISKIT as an advertiser here as well. You can check with them. But, the last time I checked with them, they used the -552 (1st gen ULF) module and I wanted to get a -522 ULF which was confirmed to work with my VZW Treo 650.
