    • 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.

    • Out this world powerful.
Style: New Model
Man, when I say this thing beat my expectations. Out this world. I never had one and always thought it wouldn't have enough power. But the battery charger is in my opinion convenient. Charges quickly. Never used a whole battery. The bag is good to keep it inside and the bits also fit in the slim bag. Love that its cordless and for what I paid after watching all the reviews and YouTube change. This is the kind of purchase you buy ounce and your done. Awesome.l dremel. ... show more

    • Excellent addition to my toolbox
Style: New Model
I’m only giving this four stars because Dremel needs to produce their battery so that it is the same as everyone else’s battery. I will say I don’t agree with Elon Musk very often but on this one point I do. Other than that, the product is excellent it does exactly what I needed to do. It was a reconditioned unit, but I can’t see how or what about it was reconditioned my guess is it was returned from by a customer who no longer wanted it ... show more

    • Perfect for travel
Style: New Model
Perfect for travel. I do mobile orthotics and prosthetics. Sometimes I have to grind a small area on the go. This allows me to easily do this without being tethered to someone’s house. I can do this where I need to with more mobility. Battery is easily charged. Comes with a small variety of accessories. Adjustable rpms for various cutting and grinding. Packs easily in my car and bookbag. ... show more

This tool is as described. Works perfectly. I didn't see that it was Reconditioned. A little noisy. Shipping was very fast.

    • Reconditioned? More like brand new!

Review Image by Abraham Abraham
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.
