I read the reviews on this item and was a bit hesitant to purchase due to the number of people stating that the device does not work correctly upon shipment; however, given the low cost, I decided to chance it and ordered one. The item came as a set of 2 receivers and 2 transmitters. The item was attractive enough and the sound quality was acceptable for the price. The problem is that neither receiver worked correctly. One would not sync up with the transmitter and the other receiver, while you could scroll through the different melodies, would not set to one of those melodies. It only rang with the default tone. The item is a nice idea, but it was a waste of time for me. I chose not to replace it, but to simply return it and purchase a more reliable product at a higher cost.
