While this unit was not at the top of Cook's list, it was recommended. There are three significant problems - the first I think is fatal. You can hardly hear the alarm go off. The second problem is to time something for 45 minutes you need to hit the minute button 45 times! The third problem is the battery life is quite short only about one month. Given the price of this unit it is not worth the money and at any price they could have done a much better design job. I am also quite surprised at Cook's rating. I would not advise anyone to purchase this timer.
