I think it really depends on the product (e.g. having Google Maps integrated is not a bad idea, because that's what you usually want to access if you enter a address in Google). But honestly, I don't know anyone that is happy with the Google Products service in Germany. They don't even show links to Amazon here, although they often have the best total price (because of free shipping). I even know a lot of people that go directly to Amazon or a price comparison site because the results presented by Google are so crappy. As results might be different based on country, region and cookie, here is a screenshot comparing idealo (a large price comparison site) with Google Product search (I just picked this specific product randomly): http://imgur.com/a/MByay http://imgur.com/a/MByay
