Don't buy these with 9 v batteries. Every year when you replace the batteries and have to buy new ones, you will thank me. The price of a 9 V versus AA is huge over the 7 to 10 year lifespan.

And if You're willing to spend a little more, get a sealed one with a 10 year battery so you don't even have to mess with it
