Bests & Worsts Reviews from Amazon

We had high hopes for this product but as another reviewer has said, its engineering is HORRIBLE. I would only recommend this product if you always want to use the same time span. I say this because you can set a default time which is relatively easy to reuse. The idea of 80% green, 15% yellow, and 5% red is great, but if you're hoping to enter 1-5-0-0-start and get a 15-minute 80/15/5 countdown, forget it. Every time I want to use the thing I have to go track down and re-read the documentation. Because of the difficulty in using it, we only use it for long tasks. As I'm trying to figure out how to use it each time, I do so with gladness that there is no one timing me as I set the timer. :-/
