The extra .410 watts of the VoxBox provides negligible transmit distance improvement over an FRS radio. This radio was type approved as a GMRS radio but it can only communicate reliably with FRS radios. The customer is going to find it difficult to use, easily breakable, poor on battery performance, and not much better in range than a good FRS radio. There is no reason or advantage to owning one of these radios. No removable antenna.
Battery life is pathetic.
Actual output power into a lossy antenna is only .99 watt making it a sad improvement over most FRS radios. Communicating with legacy GMRS systems will prove frustrating and almost impossible in most cases. This of course renders the so-called emergency button useless. Case construction is very poor. This radio will break.
