I recently bought this product believing the unique stylus disk system to be advantageous. Unfortunately, dust or dirt particles can get easily caught under the stylus disk and this caused severe scratching across my screen. I only had my IPad for a week before it was badly scratched and needless to say that I am devastated. I emailed the company to complain about the scratching hoping for a compensation and all they offered was new disks. Do not buy this product if you do not want your screen to be scratched.
