Review on High-Sensitivity Universal Stylus Pens for iPad, iPhone, Android, Microsoft Tablets, and Other Capacitive Touch Screens - Pencils with Disc & Fiber Tip for Enhanced Precision and Compatibility with Touch Screens by Adam Johnson

I have the stylus that came with my phone and the cheap one I bought in line at the grocery store. None of them worked on all my devices. I bought this product to see if I could use it for everything. I've found this to work on all my devices and I love the writing advice. It's much easier to put a signature than a finger. I also liked that it comes with two handles and spares for both ends. They also have a magnetic cap on the end for you to write on. I kept one for myself and gave it to my daughter-in-law to try.
