I would like to change my evaluation for this product. When delivered it would not charge or function. I then began to explore this stylus and found that the contacts on the "charging port" were not making contact with the pen. I used a small pair tweezers to compress and decompress the contacts (they are spring loaded). After a few cycles of this they made contact with the stylus and the charging of the battery began and the indicator LED would function. My stylus now functions well.
