Input:
I needed this selector to change music locations in my house and it does the job I need. This product works well and was cheaper to buy on Amazon compared to any of our local stores. I actually only found two stores in my area that carry selectors and the price at Best Buy was a lot higher, Radio Shack was slightly higher but not in stock.
