Just a simple timer! Easy to use and easy to see! Light up function is great and works just for what we need - just use it to time grilling meat!the lightI am a physical therapist, and used this every work-day for 11 months, then the buttons fell off, and into the trash it goes. I will spend more and hope to get one that lasts until I retire in about 15 years.Works as describedBought this for the "large" or display, only to discover that the fractions of a second are displayed in tiny numerals above the larger hours, minutes and seconds. Despite the so-called "jumbo" display, I will still need my glasses to read fractional seconds.Minus one star for coming with a dead battery. Was pretty easy to set date/time/alarm. The alarm is very quiet. Would be hard to hear with any back ground noise going on. I would like it better if you could choose to leave the back light on and would be nice if you could turn it off completely. It does the job I bought it for and I am happy with it.These are good stopwatches but they have one serious design flaw. The buttons on top of the stopwatch will fall out. You will go to use it and discover that one or more of the buttons is missing. This didn’t just happen on one stopwatch I bought three of them when they were on sale at Walmart and they all did the same thing. You end up cannibalizing the stopwatch is just to get the buttons off of them to make one of them work.This was the first time I'd ever used a stopwatch. Man these things are complicated. Its not easy for me to use but is durable and easy to read. My only complaint is that the back light doesn't stay on for for than three second and there's no option to keep it on.Perfect for what I require.Simple to use for basic workGreat itemEl problema fundamental del cronómetro es que no se ven bien los números. La lente que recubre los dígitos es curva y algo reflectante. Con la más mínima luz que incida en la pantalla, tiene un efecto de espejo muy incómodo. Esto se ve agravado porque el fondo de la pantalla es verdoso y los dígitos, a pesar de ser grandes, tienen poco contraste. Aparte, es muy resbaladizo. No tiene ninguna superficie rugosa que mejore el agarre en la mano. Da la sensación de que va a escurrirse y salir disparado. No lo considero útil.Wouldn’t recommend. It came quick but didn’t even work. Return and refund was easyProduit tel que décrit sur Amazon. Facile à utiliser.
