I got this because I will teach very quickly and need a PPT remote. This red laser is easy to use, works well with google drive, I not only switch between slides, but also control the volume. It's totally worth it, compact and can be like a pen in your pocket. thank you!

I use this during classroom instruction. It has very good range and is clearly visible from 50+ feet.
