The product itself is good and works relatively well. It does all it promises with the exception of the battery performance. The battery has a short cycle and also a relatively short life cycle. This would not be a significant problem except that the company does not support the product. They will not send or even discuss replacement parts -- including batteries. There is no where else to buy batteries as they are special made for the X5 only - simply not available! When I spoke to the product support technician I was quickly told they do not support this product in any way - no tech support, advice or parts and have no intention of ever doing so in the future. They cannot -- or will not tell you where replacement batteries of parts may be acquired and keep telling you it is not in the current product line and therefore not supported.
