I recently had bariatric surgery and you have to eat slow, I found these on Amazon and I tried it and there is a 20 second timer works perfectly, !

es un producto ingenioso y a buen precio

Nothing special. Ordered the timers, they work as advertised, and were delivered in a timely manner.

This is a good selection of sand timers that, as far as I can tell, are accurate. They're well made and come in nice colors and a good range of times. My only gripe is that the time is only written on one end, which is a minor thing and which I fixed with a sharpee on the other end. I'd buy them again if I needed more.

I'm a yoga teacher and I'm using these in my classes, to time yin yoga postures for example. These timers are elegant, non-invasive and very pretty!

These work OK... MOST of the time. But that's not good enough. They need to work EVERY time. Sometimes, they get stuck, and nothing is more annoying than glancing at a timer to see how much time is left and finding that it ISN'T WORKING. I have literally yelled "YOU HAD ONE JOB" in frustration at these timers.Suitable as a toy for children, not recommended for serious kitchen use.

Got these for my kids to help with time management. We use them for everything brushing teeth, shower, extra 5 minutes bed time.

There are eight sand timers for a variety of uses. Egg timer, game timer, time-out timer... the options ore endless. They are colorful and sturdy. I think they were a very good purchase.
