A customer who has purchased the reviewed product from Quill.
Finally found a replacement!
I use this timer when I do physical therapy. Sometimes I am asked to hold a position for 30 seconds, and I can easily set the timer to let me know when the 30 seconds are up. I also use it to let me know when the 30 minutes are up on my ACT rinse. I previously had one made by Sunbeam that stopped working after many years; this one looks and works exactly like the previous one. I was very pleased to find this replacement.
