The Pyrex Professional timer is a simple, durable, and easy to use timer that works great as an all purpose unit. It has a big, clear LCD display that shows hours and minutes big enough that you can see it from pretty far away. There are three buttons located at the bottom for changing the hour, minute, and starting / stoping it. You can use this timer for cooking, office needs, limiting yourself on computer usage, or really anything.
I have dropped this little guy multiple times and he survives without a problem. There's a battery cover on the back that comes loose quite easily (you can slide it right back on), but other than that, it doesn't show a sign of being damaged. Once you put in a new battery, it'll last a good couple months of average usage without needing to be changed, which is quite helpful. The sound it makes when it goes off is very piercing and is impossible to ignore, making it a good timer to use if you want to take a quick nap but don't want to sleep for too long.
I'd highly recommend this timer to anyone who's needing a durable, all purpose timer that works well and doesn't cost too much.
