I ordered these for my beach wedding. It is supposed to come with a PAIR, meaning two, one for each foot. When it arrived it had only one of the two in the package. I tried contacting the seller 2 weeks ago and still have not gotten a response.

Ex Output:
negative

Ex Input:
I ordered this product based on the product description that the product would function to provide WIFI capability for my dish Wally. Upon installation of the product the receiver would not recognize the adapter in order to allow for installation and setup. I called dish tech support and were not able to get the adapter to function. I requested a RMA and return shipping label from supplier. The supplier provided the return shipping label but I was required to pay freight to return the product. Also I was able to order a functioning adapter from dish for $23.00. what a rip.

Ex Output:
negative
