I've had other Oregon Scientific products and been please, but this product is very poor. It has never found the time frequency. It sits next to the other OS product that syncs all the time! In addition, the SET ALARM/Time stuff is very poor. It has a switch within a rocker. In the middle, you turn off and on the alarm. On the outside, you can set time or alarm, and move up and down in time. I found it very easy in a sleepy state to turn off the alarm AND change the time with a single touch. The up/down rocker isn't reliable either, so I've been forced to go 24 hours the wrong direction, or it just stops sometimes.
If you want an easy to use alarm, this isn't it.
