Query: Waste of Money

I actually received a monitor for my shower and gave it away, so that I could buy the Pet Sensor for my animals. Constantly, the beeping in the night that jolted you out of a sleep. Now, the monitor has completely died, it can be plugged into the wall and still shows low battery and shuts off. I still have never even been able to get the compartment open to put a seperate battery in it. The item sucks for the amount of money you spend on it. I emailed the company about the problem and they never responded, considering it died after just having it exactly a year.
