I cook a lot and when I do, I am usually cooking multiple items at once. Typically, a protein and a side dish or two. I got tired of setting a timer on my microwave (which doesn't do hours), a timer on my stove and a timer on my phone when I am cooking dinner. With this timer, I can have all of my timers set on one device and I can take it with me if I go into another room. Previously, when setting a timer on my microwave or stove, I found it difficult to take them with me!Overall, the minor "issues" that I have with the timer are outweighed by the convenience and ease of use, so I still give it 5 stars and would recommend to anyone that cooks a lot.Those minor "issues": The timer screen goes dark when you are using it. This is to save battery, of course, but it prevents you from being able to read the timer at a distance. The screen does not go completely dark, so you can still see the countdown when you are up close, but it would be nice to be able to see from a distance, as well. It does illuminate the screen during the last minute of any of the three timers, so that is nice, and you can always just touch a button and the screen will illuminate. The other minor "issue" would be the audible beep when it goes off. The timer will beep a certain number of times based on which timer is going off. While this is nice, I would prefer if the tones were different pitches, instead of just beeping a different number of times. It is my silly preference, so I really can't ding OXO for that.
