Review on Rechargeable USB Presentation Clicker W/ 2.4GHz Wireless Remote - Compatible With Mac, Keynote & Laptops by Matthew Bahri

I needed a slide advancer for class that would work with Google Slides, as that is where I build all of my classroom presentation slideshows (for convenience).I saw this slide advancer while searching through some far more expensive styles. I love that it can't go onto my finger until I've removed the computer plug in, and that when I've removed it from my finger, I am highly likely to remember the computer plug in because of the gap in the ring. (So far, I have not left the room without my slide advancer or the computer plug in for it. That's a huge difference from the other three I owned before that all were lost to classrooms when I left them behind and someone else picked them up and took them. :/)The battery charges quickly and stays charged for a while. I only teach two classes in person, but the advancer has stayed charged for several weeks at a time with regular use. (I am good about turning it off when not using it, which makes a big difference. But I think it's much better batter than I had anticipated.)It has great range for the classrooms I teach in, which aren't huge. The laser pointer works well, and I can point and advance slides from anywhere in the classrooms I'm in.
