Too small for classroom use
Extremely small. would not suggest getting this if you are in need of a classroom timer that students can see. Could not use it in my classroom

Perfect size for the application.
I was looking for a slim timer that could be mounting to shelving for a kitchen pass through/serving line and these fit the bill.

No power off option
The only way to power it off is by taking the battery out. If not, it stays on all day/night

Display background is darker than I'd like.
It's $9, so I did not have high expectations. I wanted basic, and this fits the bill. I don't mind having to take out the battery to turn it off since I only want it for occasional long exposure photography timing. But, I am a bit disappointed in the display background, which is too dark. Not enough contrast between it and the numerals, making It difficult to read in low-light conditions, or if your eyesight is not what is once was, like mine. It is easy to use, so will be satisfied with that.
