at first I was very septic then trying the product ... and YES it work with WATER! AWESOME more batteries worries !!! Cheap, green, and saving for the consumer. gives the time, date, alarm clock and thermometer make. plus it sends you a small key ring cool little caution gadget. I do not regret the purchase.
::: Edit ::: has avoided after two replacements, always the same problem, namely that the rust circuit, oxide s and breaks! malgres total respect of jobs of mode. damage cetais a good idea
