I've used it. I'm not sure of the current status of their legal battles, but they were barred from giving some of the actual genetic risk information.
That said, there are web sites available that can provide that data. One very common one is
SNPedia. Essentially they make use of the same medical study results tying certain SNP data to certain traits and can give you a report essentially as accurate as 23andme used to give.
The way it works is after you submit to 23andme and they analyze your saliva, you download the raw date from them. You can then upload that raw data to SNPedia to get your report.
Some very interesting stuff...
