Review on Digital Kitchen Timer 4-Pack - Large Digits, Loud Alarm, Magnetic Backing, Stand, ON/OFF Switch - Ideal for Cooking, Gaming, Exercise, Office - White by Sandra Getchu

I ordered 4 packs of timers and they arrived in identical packaging. The first one I opened and the display didn't work at all but was noisy. The second one I opened only half of the display worked (see picture). The third and fourth work fine. The battery covers on the 2 timers are different. The two non-working timers have the coverage shown below, while the working timers have the coverage shown above. Perhaps they were produced in different batches, they differ significantly in design. I have requested a refund.
