I gave a 4 star as I don't know if the clock has longevity due to quality and how fast it chews through batteries and it would be good if you could check the battery level via the app but as of now you cannot by what I have seen. All that aside, the timer function is great as now you can see easily how long you have left of each timer you set. The only down side is it has no glass covering the hands and face and seeing as it is in the kitchen, cleaning maybe a nightmare but will see. Would I buy again? At this point in time definitely but seeing as it is a $50 clock will see how long it lasts and may change due to life of device.
