I have been using a stylus for two years. I have tried a bunch of them mostly the cheaper versions. I received a new Kindle HD Fire for Christmas and found it was necessary to use a good stylus. I invested in the Amazon Basics because of previous reviews and extensive research on the best one. There reviews were correct. The money was well spent and the product is terrific.
Output:
Positive Review
