This little presentation clicker has really made my life so much easier as a teacher! I used to always present Google Slideshows from my laptop computer to my students, and every time I wanted to go to the next slide after walking to the front board where my slides were projected to explain something, I would have to constantly walk back to my desk to click on my computer keyboard to advance to the next slide. This little clicker has saved me from all that walking back and forth, and also allowed my presentations to flow more smoothly! There is a little dongle to insert into your USB-A port or USB-C port (for Mac computers), and there is nothing else to download. There is a charging cable included which allows you to charge the clicker and I appreciate not having to buy batteries. The buttons are very self-explanatory, and the little laser light is awesome at being able to point out things that have been projected on my screen. The only caveat is that I do not let my students touch this clicker because I do not want them shining the laser into each other’s eyes by accident. However, my students think it’s very cool every time I use it, and now I can’t imagine teaching without it!
