    Fits 8220 perfectly

    Fits my 8220 Dremel perfectly. Works great as well. Charging the battery that came with the dremel now (original battery) and will update when it's done.

    Not a good replacement for the original Dremel battery

    Not a good replacement I have been using this battery in my Dremel tool and it is larger than the original battery and fits too tightly into it. The charge won’t charge my original Dremel battery either, and it should be the same!

    Short life

    The battery doesn’t hold a long charge life when using it on high. I have to alternate with my other battery to keep my project going

    Easy exchange but still wrong part for the right product

    I ordered the wrong size but it said it worked with the dremel I have (B240) and after an easy peasy exchange I got another battery charger for my B240 but it doesn't fit properly. I works but it doesnt fit like the battery charger I got with the dremel
