Very easy to use and
Very easy to use and simple to set up. I think for the price batteries should be included. Luckily I had some handy. As a customer I would gladly pay an extra $2-3 to have batteries included. Imagine having to hop in your car to go get batteries when you finally get a slacker and decide to use it only to realize it didn’t come with the batteries. Irritating detail, easily fixable by slacker corporate management. Still a great tool and was easy to use. Recommended.
