BRAND NEW! NEVER OPENED! The Microsoft Surface Dial is a great tool to use. It is an aluminum puck sized Dial that helps navigate and make your Microsoft experience that much better. Great tool to use for artists and is a business essential to help make your work easier. My son uses one for school/virtual learning as well and he loves it. Makes learning that much easier. It is Bluetooth and takes 2 AAA batteries (which it comes with). I have one on my tablet and one on my laptop for work. I give it 5 stars. Great item to use. Brand new in stores can cost anywhere between $120-$150. I am selling this one for $80 or best offer. If you have any questions on how it works or how to get it started feel free to ask. I love the surface dial and I promise you will too.
