I just received this product today and tried to use it on my iPhone 14 Plus and my iPad. In order for it to work, I need to press it very hard, and because my phone is new, I don't want to cause any damage due to the pressure. I can't tell if the specific product I received is defective. I watched videos and read about its use, and nowhere did I see or read that it requires a certain amount of pressure to work.

Honest product for its price. I had never used a pen on a tablet before and I needed to write on documents on my tablet during remote classes. It has been perfect for this specific task. The only downside is that you cannot touch the screen with your hand while writing with the pen. I use it on my iPad mini 4 and Xiaomi Redmi Note 5.
