I read the dimensions first and knew it was smaller. It's funny that they are using BIG in the title. Please read the dimensions! Anyhow, this is a simple, about the size of a deck of cards, easy to use, and straightforward timer, comes with a battery, stand, and magnets...simple for timing testing or anything else in the classroom. If I want a larger one later, I will order off Lakeshore.
