It looks good, can be fixed easily and reliably and clearly legible displays the current and the minimum and maximum temperature of the night or the day.
Even a change of location was no problem, the supplied adhesive corners for durable enough.
Although the thermometer is still suspended me some wind and rain, no function default was recorded so far.
Should also be noted that the display in the dark, of course a little more difficult to read.
All in all, a beautiful, functional and, moreover, fairly inexpensive product.

Update 5/12/2014: After the thermometer is now only five years in my possession, I can only confirm my initial impression: It still works reliably. So far, a single battery change was only necessary. The long-term durability is so fully given!
