I appreciate such a well-built product. It works exactly as advertised and the only reason I didn't give it 5 stars is because the side switches are a bit small. You have to use a pen or the tip of your fingernail to turn the different channels on or off, but this is a minor issue. Good product!

I needed something to increase efficiency because cell phone use reduced productivity. It starts working three seconds after turning it on. The phone shows no signs of loss of signal or malfunction. The user therefore assumes that this is a service rendered. Magic!
