This is my second set of these pens - I lose my pen about every six months! I use them with my Kindle Reader and Kindle Fire to surf the web, email, play word games like Bejeweled. games and puzzles. I use both ends alternately; it just depends on what works best at any given moment. To be honest, I don't find a huge difference between them, but it's enough to make them work differently under different conditions (screen heat, screen humidity, whether I'm using my right or left hand, etc.). I strongly recommend them; they work well and wear well. My only disappointment is that they are neither slightly longer nor shorter than most other pens.
