Ideal para marcarle el tiempo a los peques- Puedes darle el tiempo que quieras a cada color o, sencillamente, tiene una opción para poner el tiempo total y ya el el semáforo se regula solo para darle la mayor parte del tiempo al verde, un poco al ámbar y algunos segundos al rojo.Es muy visual, para los niños va de maravilla. Incluso lo pueden usar cuando crecen o hasta los adultos. También puedes ver la hora. Y tiene aviso sonoro.Genial.

Llego dañado no emite ningun sonido y no pudimos hacer la devolución

Aunque debes usar dos tipos de pilas, una para la pantalla del reloj digital y otras para el semáforo

Me a funcionado muy en el aula

Je kan elke kleur apart instellen. Als de tijd bijna om is gaat de kleur knipperen. Je kan het geluid uitzetten.

Buenisimo timer para ayudar a los niños a tener nación de los tiempos, lo único malo es que fijas la hora y por algún motivo esta se cambia, pero no afecta su verdadero funcionamiento que es como alarma, nos encanta!

Al usarse dentro de salón de clases y con varios alumnos al rededor, el sonido resulta bajo.La luz indicadora al estar viendo hacia los alumnos limita al maestro a darse cuenta si el tiempo ya terminó y como el sonido es bajo hay veces que no se da uno cuenta

Excelente producto para mostrar y enseñar el manejo del tiempo a los pequeños, muy fácil de usar con un excelente diseño.

Me encanto su iluminación que tiene regulador de volumen, sería bueno que ofrecieran el cargador para ahorrar cuando se pueda en baterías, lo malo es que una vez que inicias un ciclo del timer no he encontrado la forma de interrumpirlo, imagina que por error lo pones a muchas horas, tendas que esperar a que termine o sacar las baterias usando un destornillador.

Aun cuando los dispositivos móviles incluyen cronómetro, el que este Time Tracker tenga cambios de luz y sonido pone más en alerta a los alumnos cuando realizan exámenes o actividades en el salón.

I hesitated to buy this for years due to the negative comments but I'm so glad I finally did! I find it easy to use (takes a couple seconds to set). I like that it is battery operated, I personally wouldn't use the ac very much as I need it to be portable. It has a sound when the colour changes and when the time runs out, there is a volume control to adjust it for those who are noise sensitive.Overall I am very happy with it! It has really helped my child that struggles with transitions and is very visual. I think it is great for any child but is particularly useful for those that have adhd/autism.

UPDATE (NOV 2013):We had another child in March of 2012 and he has finally reached the age where he is chatting a lot, very interested (in EVERYTHING), can communicate with us (modestly), and we can in turn communicate back to him. I love 18 months old!!!Due to the structure of our home, we decided to setup his crib in our bedroom. It has been working out very well, but in the past couple months he has been waking up at a ridiculous hour (5am or earlier) and will not stay quiet. If I get out of bed and talk to him, cover him up with his blankie, and say "It's night-night time..." he WILL lie there quietly until our alarm goes off or one of us gets up to go to the bathroom. Because of his responsiveness to my chats, I decided to break out our Time Tracker once again. It has been in a drawer since our other Son turned 4 years old and outgrew time outs and sleeping timers.I set the Time Tracker the same way I did for our other Son (12 hrs Green; 50 seconds Yellow; 10 seconds Red...yes, this Boy will sleep from 6:30pm to 6:30am, no problem). On the first and second night we setup the Time Tracker, our Baby Boy thought it was fun to point at and scream. But he soon lost interest in it and now I can turn it on, put him down for sleep, and if he wakes up before the designated time (6:30am) and starts making noise, I walk to his cribside, remind him that "Green Light is Night-Night" and he will honest-to-goodness either go back to sleep or just lay in the crib with his blankie & stuffed animal, sucking his thumb, and stay quiet until the Time Tracker turns Yellow (and then Red). Most times he is awake and starts yelling once the Tracker turns Yellow because he is excited to wake up. But some other times, he falls back asleep and he completely misses the Tracker turning Yellow or Red (no issue there...if he's asleep, we let him sleep!).The Time Tracker has worked for both of our boys and we've definitely gotten our milage out of it considering I bought it back in 2009. I'll probably use it once our youngest is old enough for Time Outs too. And once I pulled the device out of the old junk drawer, I had no problems remembering how to set and reset it...it really is a great device for kids!-------------------------------------------------------------------------After reading many of the negative reviews on the Learning Resource Time Tracker, I was hesitant to buy it thinking it would break right out of the box. Not true at all. In fact, while it is not the most quality product I've ever purchased for my 2 1/2 year old son, it is definitely not the worst. It is what it is...and it does what it does...and it does both very well.I first saw the product on Nanny 911 and I did think about it again until I started having difficulty keeping my son in his time out spot without having to sit right next to him to keep him there. I combined the Time Tracker with the Take Out Time Out mat (overpriced, but cute) and now I hardly have any problems with him finishing his time outs. He thinks time outs are interesting now and he cannot wait to finish and hear the "Time's Up!" announcement so he can play again, while knowing that we are happy with him for doing his duty.While the Time Tracker may not be the easiest thing to program, as others have said, once you do it once it's pretty easy. I have gotten so used to it that I can change the timer from time out, to nap time, to overnight sleep time in less than a minute. I set it to all green on "manual setting" and only make it turn yellow for the last 50 seconds, and red the last 10 seconds. Seriously, those reviewers who say it's difficult are simply techno-phobic or lazy. It's not hard and all...and my son loves knowing that there is a set time on all of his duties. Hearing "Time's Up!" is one of his favorite things now.Finally, again on quality, this is not a toy. Do not let your kids play with it or it will cease to work. Let them see it, touch it, but only once. Tell them it is not a toy and keep it out of reach. It will break if dropped, so my solution is to not drop it. Problem solved.Get this product. It's pretty darn cool...
