Despite the bad reviews I read about this product, I can say that it's actually good. With the latest firmware it works very well. iOS app. works great and gives good information. Gets a little warm with use. It's better to put it outside but not in the sun. The battery life is decent, but 2 batteries are needed for 12 hours of intensive use. Be careful with the seller you buy it from. Some come in original AT&T packaging. Some from China with different packaging and wall charger but it appears to be the same product.
