Pretty bad 26

I chose this story for its super readable display because I needed a countdown to a drive for a hearing. It is true that the image conforms to reality: the numbers are very readable, but ...
First surprise: from the first test, a button is stuck, making use impossible. I was able to loosen by dismantling the unit. Second surprise: there is no on / off switch! To stop the machine, you must remove the battery ...! And the battery cover is also very difficult to remove. Third surprise: at the end of the countdown, one is obliged to undergo a ringtone: useful but inadequate for training on the day of the hearing before a jury! Fourth surprise: this marvel of technology is not able to tell the time!
In short, this is really not expensive, but I would have given double the price for a better product!
