The star ratings above are based on PC Pro's Reliability & Service 2009 survey, which took place between May and August 2009. This year, over 14,000 readers took part: we asked about the customer support they received, the reliability and quality of the products they bought, and whether they'd buy from the company again. We then combined all this information to produce a star rating, and the company with the highest rating wins. If any companies were close runners-up, they win a Highly Commended award. Note that for the results to be statistically valid, we need 100 people to have given their feedback on the company. This is why many smaller companies aren't included in the table.
