Query: Timer review

I like this product a lot. The numbers are big and easy to see from a distance. I use it to time many things like cooking, working out and using facial masks. It has a magnet in the back which can attach to magnetic surfaces. My brother actually takes it to the park when he exercises and attaches it to the monkey bars. It also has an easel so it can stand up on a table as well. Only bad thing is I haven't figured out how to turn it off so I always have to take out the battery after I use it.
