I bought this supplement screwdriver tool box with two batteries. I'm used to DIY at home opportunity and I'm very happy. It is light and not have wire that takes in established or the workpiece is very convenient. I was afraid of his cutting ability but I was pleasantly surprised. it is effective and rugged, have two batteries allows to use continuously. The only negative that I find it is the particular noise it makes it looks like a bread knife electric ;-). In short perfect for my use
