The Lenovo Precision Pen 2 is a great stylus for tablets and laptops, with a long battery life and easy setup. It is lightweight and has a hexagonal shape for control of the pen, but the buttons should be further down and the pen is surprisingly slippery when writing. It also has an eraser function and a lasso tool function, but these functions are pre-programmed. Overall, it is a great product and worth the price.
