Great tool, best of the line up
I have the 4200 EZ-Change but needed cordless. This is brilliant and whilst the unit is a little bigger, that doesn't matter to me as I use it with the flex shaft. I couldn't tell the difference between this one and the corded one to be honest. Batter life wasn't brilliant but it's fine if you know what to expect. For anything that needs a longer application, I'll use the corded one anyway.

Really good bit of kit
Really great multi tool, I use it for carving but it comes in handy for other DIY. The only thing I do feel could be better is the battery life but it does charge quickly and there are two batteries in the kit.

Large and heavy
Nothing wrong with it. I opened the box, picked up the dremel and it was like carrying am iron mallett. It was just too big and heavy for my hands. Returned and refunded
