I have tried several stylus (styluses? stylii?) for my new iPad and found that the ones with the erasers on the end seem to work the best. So since that knocks out all the cheap ones, the cost for a good iPad Pro stylus is going to be over $50.00
The apple pen worked, but it was:
This is the one I found to be fair in price, and it has the fat eraser at the top for better control!
I really like the Fifty Three because it feels like an old mechanical pencil, and the grip allows for better motion. If you use your iPad a lot, grab one of these – you’ll love it!
