Review on Creativity Acrylic Non Toxic Classroom Assorted by Sonja Garcia

The timers work BUT when we tried to replace the battery with a US made AAA battery the timers didn't work. The Chinese made battery that came with the timer was a slightly smaller diameter so the American made battery didn't fit properly. I have sent three emails to the company and received no response. We bought precision timers a few years ago and you can change the batteries and the timers work fine.
