The power of a community of users giving their opinion on a certain product is what TestFreaks takes advantage of to guarantee the quality of the products recommended on the site. I am talking about the Spanish version of the well-known TestFreaks.com, a site that allows consumers and experts on the subject to be responsible for the recommendations made on the web. Although this version is not as mature as the original, it already has quite attractive content. Camcorders, Mobile Phones, Digital Cameras, DVD Players, MP3 Players, Multifunction Printers, Printers and Televisions are the categories currently displayed on TestFreak, with expert comments, forums, videos and photos of each of the products evaluated. It can be seen on the same page that they are preparing to include other categories such as Home Cinema Amplifiers, Nintendo GameCube Games, GPS, Home Cinema, Monitors, LCD, etc. The note displayed on the page of each product allows visitors to get a quick idea of the feedback received by those in the know: consumers. Together with the description of the experts, readers and manufacturers we can see the price obtained from various sources, allowing to have all the necessary data before making the final decision on the product. As is usual in web 2.0, the success of this type of site depends on the collaboration carried out by users and, in this case, on the movement on the Internet about the product in question. I have tried the search system to see what they say about my new mobile (samsung u600) and I found, nothing more and nothing less, that with 99 opinions from 18 different countries with an average score of 7 out of 10. The opinions come from the most diverse sites, in several languages (only local ones can be filtered). TestFreaks was founded by Kristofer Arwin, Magnus Wiberg, and Martin Alexanderson, who previously founded the famous price comparison site PriceRunner in 1999.
