    I was very surprised at the power. It does alot of jobs that keeps my big 1/2in drill on the shelf. I wish i would have had this years ago.I use it daily and would feel lost without it.I have never had a problem with it keeping a charge like similar products do. Thank You BLACK&DECKER.

    Great Tool
    I already had one of these in my workshop. Kept having to go to the shop to get the tool when I needed it. So I purchased one to keep in the house. This is my most used tool, from replacing door knobs to hanging blinds. It is light, easy to use and the screw holder makes it a super tool to use.

    I use it for hanging pictures, putting up blinds, putting together and taking apart furniture. Having moved house a few times in the the last few years it's been my extra hand.

    They thought of everything the holder so you can use force. The power selection and of course everything all in one place and holder to keep you organized. THANKS BLACK AND DECKER!!

    I owned the li3000 for five years. I have used it and abused it and it keeps going. Even now after all the abuse I could throw at it does its start acting up. I am getting the Li4000 for Christmas (Don't tell the wife I know) if it is 1/2 the product that the Li3000 was I will be more than pleased! PS I wish there were more stars because this product needs more than five.

    I use this tool around the house, but I'm a busy DIY'er. I have used this tool all the time, it's fantastic and hasn't let me know.. I'm happy with my investment and will recommend this product. I have bought alot of tools in my lifetime but this little guy is typically with me on every project.
