Title: Yes, it is a piece of crap.
Product review: I purchased this detector about 8 months ago, and just have others said there is an issue with battery drain and false alarms--as I discovered in the middle of the night. The major issue now is the constant "ERR" code that comes up causing the unit to beep LOUDLY. I have since disconnected it. The manufacuter date on the back is July 2006 and if the sensor is "dead" what the heck is the point of buying something so unreliable? Save your money and patience and find something more reliable.
