Question: Do these timers have a warranty? I've thrown my packaging away and am unable to tell. Thanks!
Document: That's it. The other buttons don't work or beep, so bumping them doesn't do anything. I hear the beep, and look at it. It's pretty easy to tell what happened and fix it. Usually I've stopped it, and I restart it right away and have only lost a second or two. In several years of ownership this has happened maybe 3 or 4 times.What I like/love about this timer:  Neckstrap feature is great; it's light, and shaped well for hanging around your neck.
This is just what we needed. For years, my otherwise-perfect wife has set timers in the kitchen of our very large house, then gone to other rooms while the meal cooked. When the timer beeps, she's so far away that she cannot hear it. What a brilliant, yet simple idea to have a timer that she can hang around her neck! I must admit that I've done the same thing, so we bought 2 of these.
I've one of these for 5+ years now and have yet to find a better timer. Setting the time is easy. Being able to just enter the time without using those annoying arrow keys is a joy. Why can't other manufactures use numeric keys? I can't tell you how many times I've missed the correct time using arrows.
I purchased this timer when the one on my range broke. I use the timer function several times a day, and really like it. The timer sound is loud and persistent enough that it can be heard from several rooms away, but you can also hang it around your neck. Usually I leave it on the refrigerator, thanks to its magnet. It is easy to operate and turn off. It includes seconds, so you do have to make sure you add two zeros at the end whenever entering minutes.
I love this timer. It's tiny. I put a red striped ribbon on it to hang around my neck, then drop it in my shirt pocket. It's accurate and so easy to use once you get used to the tiny buttons. It keeps ringing til I turn it off so I don't forget.I hurriedly ordered a second one so if this one fails I have another still in the packaging.I've had the same one in use for 3 years and it's still working.
The alarm on this is loud enough to hear a few rooms away and unlike timers that stop chirping, this calls until you come. It is portable enough to fit in your pocket or around your neck. If you have sensitive skin, you will need to change the cord it comes with.
I've ordered several of these timers. I love being able to wear it around my neck and move around while my food is baking or cooking.
The long cord on this is great for wearing around my neck to wake me from naps I take in my car at work, to remind me to take medicine. I've had lots of timers and this is my favorite, and EASY to use. It has a pretty loud alert.
I can live with this.As someone who's been buying timers (it seems like forever) this is the ultimate and recommended as the best I've ever had.Yes, it does have a small round battery. Also something I can live with, considering the quality and functionality of this product.
I love my Polder clock timer.I've had many timers before but this oneis the best. I like the all digit keyboardthe most. My last timer required me to pressthe minute button to increase the minutes.This timer makes it easy to set the exacttime that I need.I use it in the kitchen where many foodsneed to be timed.
Answer: I didn't see one.
