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

I bought it right before the pandemic started. I used it for a while for in-person teaching, and it was working pretty well. Then I stopped using it because we converted to online teaching. Just two months ago, when my graduate student tried to use it for her defense, it didn't work at all on both flipping the slides and turning on the red light for pointing. When I charged it and pressed the button of the light, there was a light pointer. I was kind of sad since I didn't use it for a long time. If I can get a replacement with a functional one, I would be appreciated. Thanks!
