If you are looking for a pointer that is reliable, affordable and easy to use then this is it. I am a fire brigade/EMS instructor who gives a lot of lectures. I need to connect to different computers regularly. You can use this pointer to easily navigate forward/backward through your PowerPoint slides. The buttons are responsive and you may be more than 30 feet from the computer. The laser pointer is also efficient and works well. I am very satisfied with this product.
