I originally bought the Boxwave stylus for my iPad which worked OK for a while but then started to loose it's responsiveness. After fitting a Media Devil screen protector it was almost unusable, I had to press very hard to swipe the screen and drawing and handwriting on the Noteshelf app was impossible.
I thought that was partly due to the screen Devil screen protector so I sent an email to them. To my suprise and astonishment I received a reply within a day saying they were going to send a new pack of screen protectors along with one of their styluses, even though the problem didn't lie with their stylus. I was a little apprehensive as to the outcome, but what a difference the Media Devil far outperformed the Boxwave, I can now start drawing again!
This is a very good firm to deal with, it's a pity everyone doesn't react like they've done.
Their stylus is second to none and I'll give it A1+++ and five stars! ..........Buy one with confidence!
