This is an excellent drum machine, very easy to use! The drum sounds are phenomonal, they sound just like real drums and there are many drum kits to choose from and even modify! It also has a brand new internal battery. The keypads are touch sensitive to help make the drums sound even more realistic. It's in good condition with very minor scratches from normal use. Also has the classic 808 drums that many hip hop artists use in their songs such as the Beastie Boys. Here's also a link to the owners manual :
