Review on Rotatable Touch Screen Pen Disc Stylus for Touch Screens - Granarbol Universal Stylus for iPad, iPhone, Tablets, Samsung, Kindle & All Touch Devices - Includes 3 Replacement Tips by Joe Roberts

I have a new touchscreen ordering system at work and wanted to prevent calluses on my fingers with a touchscreen pen. I read the reviews and decided to try this one, but wasn't impressed at all. It only works maybe 75% of the time on screen. I also tried this on my phone to see if that was the system I was working on. Same problem when using on the phone. I got a free cheap touchscreen stylus that works better than this stylus.
