A must-have organizational tool. The label, Smart-Key Finder Wireless Tracker, isnt the best name for this undeserving product. I waited for my iPhone to locate the Bluetooth Tune2Air and I plugged in the code provided with the directions. Have to jiggle the key in and out of the lock cylinder, but it does function. The bass and treble are there and detailed enough without pushing for your unreserved attention. These aren?t the original ones. I would prefer a sturdier body and construction but still good quality. I had to order two sizes smaller than what I normally wear. Looks purple in the images Beware of having to return this because this seller does not provide any box, they send it directly in the box the boot comes in, the one youd see in a store, so youd have to find a box suitable for the boots if you wanted to send them back.
