Excellent stylus. It offers very little friction while writing and is very well built. I was quite surpriesd by the build quality. The plastic end of the stylus flows smoothly on the screen and is very pleasant to write with. The other, rounder side is also good, however i've noticed that if there is any grease or if the screen is dirty, the nib gets clogged after a little while and it stops writing as smoothly as in the begining. I recommend buying the replacement tips along with the product, as it does not ship with any.
THANKS !!!
