It says it's for iPad Pro 9.5. and thats what it likes. I've been using it 3 hours a day for about about three weeks, first battery change. No bluetooth to keep dropping and interfering. No need for all the $$ iPen accessories. It works with every app. I've used, (53), Brushstroke, and it pin points every touch smoothly. It fits in the pen holder on cases. I have OMOTON glass screen protectors and theres no scratches or problems. It's has a smooth finish an I've dropped it 4 times (notonpurpose) before I swirled some hockey tape around it, the drops didn't affect its performance. It also shuts off when you forget. I haven't used a stylus much because they were expensive or clumsy. with this Pen and a finger it opens up a whole new ease of App.control an hygiene. This is a smart choice.
