Bought this today at a "mom and pop" hardware store. At $13, I thought the price was quite reasonable.

Searches for it lead me to believe the company is no longer in business though.

It has an alarm built in that detects movement a certain number of times and then sounds a 110 decimal alarm. Resets itself etc.

It uses 9 LR44 batteries which last around 2 years.

I think it is closer to 90 - 100 decibels.

What do you think?
