I used this product one day.Everyone i talked to complained about it. It works ok if the two devices are no more than 3 ft from each other and in sight of one another. When i called coustomer support using the device the Rep. said we had a bad connection,so i turned off the device and the connection was clear. The Rep. then gave me the run around, something about buying it through Amazon so they wernt responsable and i needed to take it up with them. So you might say im not happy with my purchase
