Product review (1 stars): rubbish!
shipping to Hawaii took nearly 2months???  Did someone swim it over? Forgot that I had purchased this item(s) purchased 2 units, installed the batteries at the same time and after a month they are now 15-20 seconds apart on time!  Don't want to know if the humidity reading is correct if the "time" can't be accurate...  One of those "you get what you pay for items"
