This gets hot after inflating the tires of one small SUV up to the recommended pressure for each tire. A bit of a bummer, because we have two cars. But on the plus side, it's cordless. Not having to take out an extension cord is a real convenience.

I don't usually read too often but, decided to start reading from a list of top 10 books for leaders. I saw this in a TED talk and just had to read it. I am about half way through and Simon's insights are very useful.

Ex Input:
This alarm is sensitive and loud. Prefect for what we need it for. Our lift station doesn't always work and would flood the basement occasionally when someone showered. This alarm alerts us as soon as a little water comes up the floor drain so we can address the problem immediately. We can hear it from the main floor. Perfect solution until we can get a new pump. So much easier than cleaning a flooded basement! The only issue that we had with this os that the screw on the battery compartment is very small. It came with a small screw driver (about the size of an eye glass repair screw driver) but the screw was too tight to use that. It took us multiple tries and a different small screwdriver to get the screw out. Fix that one problem and you've got a great product for a great price!
