I purchased the book only to have it arrive in poor shape, missing a page...had some pages stapled into it. There was nothing written about this book, which is why I'd ordered it. Will not purchase from here again.

When i plugged in on first time, sparks appeared from it, as soon after connecting, some electric shocks came out. The charger seems ok but obviously this is not designed for Lenovo Vostro 1520.

Bad review

Great price on an awesome tool. I've used it for 2 years now and have zero complaints. I would definetely buy more Milwaukee tools from Amazon.
