Reviews tend to be biased anyway, how many people do you know who rush out and praise their web host, if it doesn't work they complain and may do publically, if it works how many people rush out and tell people or do they just get on and use what they've paid for?
A satisfied customer may tell someone about their host in conversation (that's the best form of referral you can get

), but I doubt that they rush out looking for review sites to join
