We received this tea timer as a gift several years ago and it has stood the test of time. Very simple to use. Easy to read large digital display. It has preset buttons for 1, 2, 3, and 5 minutes. At times another preset for 4 min would also be convenient. However, any time can be selected with the “set” buttons. Requires two # 357 “button” batteries which are not as inexpensive as AAA batteries. However, they last a long time and can be purchased less expensively at Wal-Mart versus Radio Shack.
