Query: This is not a UC-EC cable!

Although the description says this is a UC-E6 cable and it is shipped in a box that says Nikon UC-E6, what you get is UC-E4 which does not fit the S3100 as described. If you need a UC-E6, type that into the search heading in Amazon and you'll find many options that are actually the correct product. Good luck!
