I bought the Action Bundle together with the LG G3 and can only say it was the best decision I have made di. The clock is very persistent and I have to be reachable at work constantly, the clock awesome. I can make the phone on silent mode and thanks to the clock still escapes me no message or call. For me personally, very effective. The associated applications are from day to day more and I think in the future, these clocks are perfectly normal. The operation is very simple. Battery lasts ca.2,5-3 days. (Standby mode)
