This looked like a good product, so I ordered three. I thought that would make up for the high shipping & handling charge of $3.99. When they arrived, shipped in a small envelope, 4 oz. first class, costing them a whopping $1.39, they had charged me $3.99 each for a total shipping-handling charge of $11.97. To top that off, out of the three, only two worked. Want to get ripped off for junk and robbed for shipping, buy from Amazon and BlueProton. Amazon shows you an invoice before you push the final purchase button and even emails you one. Does it show shipping charges? Not way.
