Very good product, nice design and easy to use. To make it a world beater would be to have an audible alarm as well as vibrating, even if that were in a premium priced 'de luxe' version - sometimes the vibration only can be missed, for example if you happened to be taking a shower/bath at the time of an alarm and had taken the watch off? This could be built in with options 'Vibe & Ring' or 'Vibe Only'
Still most pleased with it, and the delivery was super quick
