I have had the product for a heavy three weeks, but I have only used it about 5-6 times...
At first, I thought "Wow, good deal especially for its price..." but after the third day, when I tried to use the timer, the sound got stuck and the whole system froze... no next, no stop, nothing... I had to remove the battery and that requires unscrewing 6+ screws...
I thought it might be a coincidence... I tried using it again and after two presses, it seemed to be working fine, but then it started displaying random numbers and changing the time to whatever it wanted...
Now it just sits on the shelf..
