Question: Which driver is it on Wacom's website?
Document: I purchased this for use with the ASUS Vivo Tab 810. It is a tablet with an active digitizer as well and it works wonderfully. The second side click button does not work for me but i believe that is a driver issue with my specific tablet
If you haven't tried this pen, you might be missing out...Two side buttons, rounded eraser end, about the same length as the stock pen...personally, it's more accurate for me than the Wacom Feel stylus, on my Surface Pro 2.This is pretty much the closest thing to a full Wacom stylus I've used on the Surface...AND it takes the full-size stylus nibs from the website. FULL WIN.
While not as substantial as say a Wacom pen, it has a great surface texture, is a little thicker and just /feels/ like a better made product. It doesn't feel cheap and disposable like the Surface pen did.- Second, probably the most important thing. There is no dead zone on the tip.
Used it on my Lenovo Thinkpad Tablet 2 and now my Surface Pro flawlessly. Both buttons work. It does feel lighter than some other styluses, but where can you get a solid two button Wacom penabled stylus for this price.
This specific product has replaceable Nibs (the end point) and a slot to attach a lanyard.The Good:The pen is well weighted, it doesn't feel as Flimsy as the Surface pen or Lenovo pen. The two buttons are not too in the way of holding the pen, but not out of the way of being able to press them.
This pen is the best digitizer pen I have use on the surface. This is the third digitizer pen I have used on the surface. I do miss placing a pen in the charging port. But the gains like two buttons on the side vs one is great. To get full use of the pen go to Wacom web site and download the drivers. Look for the legacy drivers. Then choose Tablet PC, and click on what ever OS like Windows 8 for surface Pro 2.
This is very convenient if you miss being able to middle-click a link to open in a new tab.If you're looking for a better stylus for your Surface Pro, this is definitely the one to go with.
This is hands down the best stylus. Unlike some of the more premium priced Wacom pens, this one has the eraser function like the official Microsoft stylus. However, it goes above and beyond because it has two buttons on the barrell and can use the different Wacom nibs, a feature the Microsoft pen lacks. This is great because you can switch out the nibs to get a more paperlike feel for writing notes or drawing.
There's not a lot of two button styluses out there and this one is pretty reasonably priced. I like it.
The only other 3rd party two button stylus out there is like 80 bucks (the mod-book pen), so this is a fantastic deal!While I haven't tried other alternatives, I can absolutely recommend this pen if you're looking for a replacement or an upgrade to the default Surface pen.
Answer: You want legacy drivers and the one you want is for tablet PC, then choose your OS.http://us.wacom.com/en/support/legacy-drivers/
