Review on Enhance Exam Performance with Top Score Watch v2 - The Ultimate SAT, ACT, and PSAT Digital Timer for Optimal Pacing by Nancy Bryant

1) A kid had an old version that worked fine for two years and then failed. I ordered a new version for the second child. Everything seemed fine but the mechanism itself was installed upside down which was an issue as the outside tabs were marked as a properly installed mechanism so I sent it back with no issues. With the new battery, the old watch worked perfectly. Glad it's working now, usually signs of low battery are obvious, for some reason the clock wasn't working properly when the battery was low instead of just dimming. If you have business hours I would give them 5 stars as they work as advertised.
