There's a neat site for comparing similar products, including their reviews: wize.com.
Let's say, you're looking for a refrigerator. You can put refrigerator in the search box and the website will come up with a list of all the refrigerators out there. You can then narrow your search for a refrigerator by price, key words, brand, colour. etc. There is also a 'compare' tool for when you're trying to choose between a few models. I particularly like that there are reviews of the products. Reviews often highlight little issues or design features about a product that manufacturers don't think to mention.
Whether you are looking for a refrigerator or a car seat for your child, wize.com is a great tool for making sure you get the best bang for your buck.
