Can We Have Product Liability Claims

Sometimes I will curious that being a consumer, do we have right to sue a seller when we found that they are selling something that overprice or something that might injure people? I am not very sure about that, but according to my friend. We can find a good product liability attorney to help us for product liability claims if you are injured by a product. I think is good to know more about this kind of information, so that we can get help if this really happens.
