  • It's good and will do the job
Style: New Model
I did not select refurbished but it is. Which dose not take away from function. You might have to figure out how to put in and remove attachments but it's a pretty simple mechanism.

  • Refurbished, but with a minor flaw
Style: New Model
Received just today, haven't used it yet but it seems to run OK. There is a chunk broken out of the EZ TWIST nose cap (see photo), but it may only be cosmetic and not bad enough to send back - so I deducted one star for the damage.

  • Reconditioned? More like brand new!
Style: New Model
Saved me 25$ and feels like I got a brand new. Came in an official dremel reconditioned box which was super legit a little worrying but opened it up and found my dremel looking brand spanking new. Love the deal no need to buy a absolutely new one unless the reconditioned are out of stock.

  • The best cordless handheld dremel
Style: New Model
I love the portability of it, that it doesn’t take long to charge, and dremel bits fit this. I like that it comes with its own carrying case that holds it and it’s accessories. What I don’t like is how big and bulky it feels in my hand, but then I do have small hands. That would be my only complaint. I like how I can carve anywhere I want now within reason of course. No sitting at a restaurant carving on wood, but I can go sit at a park, on a bench in my front yard. I love that part best! ... show more
