I'm not so sure.  I haven't noticed any problems in their data (though I haven't done extensive testing), but in my opinion it is a bad sign if there's no way to contact them.

e.g. 2004-11-01

GS['2004-10-28/2004-11-03','Low']

             Low
2004-10-28 95.80
2004-10-29 97.43
2004-11-01  9.12
2004-11-02 98.50
2004-11-03 98.68
