Look at both good and bad reviews. Most people will tell you what they do not like and you can decide better. Any review that does not tell you what could be better could be paid reviews.
I like to go to store and see product instead of going to website and not being able to look at something. I also like being able to return it at local store easier than shipping it back and waiting. The only thing i buy online that i can not go to local store is domain names and web hosting.
