Query: Doesn't fit, isn't right product

I did a search for a 27910 replacement battery, read the reviews, and bought this one.Turns out it's not a 27910 battery, doesn't even come close to fitting in my phone, and now i have to decide whether it's worth $5.75 to deal with returning it (probably not). Especially since this means finding a local store to buy the replacement i actually need.I'm very unhappy with the misrepresentation.
