Hey Andy!
I have a few suggestions but we don't have anything we'd necessarily recommend, just one's that I've personally heard are pretty good.
So, some options:
GOOD - https://www.amazon.com/Wireless-Presenter-ESYWEN-Presentation-PowerPoint/dp/B07D7X7X2M/
BETTER: https://www.amazon.com/dp/B009K1PYG0/
BEST: https://www.amazon.com/DSAN-PC-MICRO-Programmable-Controller-2-Command/dp/B01MV74DNO/
The last one is the most expensive, but the most reliable from what I know
Let me know if you need anything else!
