Query: Counterfeit

I purchased this product with the note: "Sold by MarginMart, Inc. and Fulfilled by Amazon." I thought it was a great price for a USB extension cable at $3.99 and eligible for free shipping.When I received the actual product, it was packaged in a clear plastic bag with a sticker in very plain fashion stating that it was a "Belkin F3U134-10 USB Extension Cable (10-Feet) New." I've worked with Belkin products before, so I was expecting a pretty sturdy cable with their signature USB adapters (as seen in the photo for this product). Instead, it was a pretty flimsy cable with adapters that seem to hold only loosely to other USB ports and cables.Suspicious, I looked up the actual product number on the Belkin website. The product pictured there is nothing like the product I received and retails for $34.99. The product sold by MarginMart is a counterfeit.
