Seems to be very good ,easy to understand and use,persistent ring. During virus took a long time to arrive!

This behaves exactly as I expect it to, except that it needs replacing more often than I'd like. I've owned at least three of them, the last ones I bought were in 2015, which died and I bought another in 2021. That one's died and now it's 2021. I bought two others (different brands) in 2015, though, and they're both still going strong. For the price, I expect it to last more than 2 years.

This is my second CDN timer and I love it. It is my second because the first did not survive the swim in the cat bowl. Not a product problem, an owner problem. I've had the first one for two years and love it. It is a timer/count-up/clock item. When using it for cooking and baking, it counts down to zero, rings for a minute (and I can hear it 20 ft away in another room) and then counts up until I turn it off.

This is a timer I used to use when I worked at Starbucks. Just love this thing.
