That clock is very good but grossly over priced. I kind of know of the designer, I actually worked on his wireless nurse call system in my previous job. Ironically, the built in clock on this system was quite possibly its only major fault. It kept time within +/- 10 mins a month. I was constantly called out to adjust these things. I have heard that early versions of the LED clock also kept time less than perfectly but the problem has since been rectified. All told - $180 is just way too much of an ask. No thanks. Oh! and I'll add that it took almost 2 years to develop !!! (This would possibly explain the price tag)
