I like that you can create your own profile so that it's easier to share information with other people, if the site is down or you have an issue then you can't log in and that can be frustrating. You can't compare multiple items at once, but they say that this will come soon. If you are looking for a way to quickly compare different products and save them to a list then you should try out social compare. It helps you track all of your purchases and saves time by comparing products online rather than having to go through each item one by one.
