Query: Great Keyboard in every aspect

Apple products are a little expensive but they are worth it. It looks very elegant. Save a lot of space. Was very fast to setup. It has long range, I even use it to play Guitar Hero on my Macbook Pro and use it as a real guitar. The reason I needed the keyboard was to protect my Macbook Pro at work from stains when you use the keybaord for a long time, my wrist and part of my arms sweat because of the heat. Also, if you use a watch or bracelets you might scratch it. The best thing abouthe keyboard is the battery life. I use the keyboar about 50 hours a week and the batteries that came in with the keyboard have lasted for more than 5 months!
