Review on AIMILAR AY4053-Black Digital Countdown Timer: Upgraded Big 999 Days Count Down Clock for Vacation, Retirement, and Wedding by Josh Zepeda

. That is not right at all. In just 3 days that's over 20 seconds. This can work well for 1 hour to 24 hours, but if it's 20 seconds faster in 3 days, it'll be off by almost 2 hours after 999 days (which is advertised). If you don't care about inaccurate times, that's fine, but it's not for my purpose. Since I want my time to be accurate to the second, I'll probably let it run until there's 1 day left, then change the timer again to be more accurate. If those who bought this product from Alibaba want to report it to the manufacturer, please let them know that there is some kind of rounding issue making it wrong. You can say that the quality check was not performed if it was disabled for more than 20 seconds within 3 days. I'd even be willing to bet that if you set 2 of them to the same time they'll probably show up correctly initially, but give them 3 days and I'd be willing to bet they'll be a few seconds off both . real time and each other.
