Bought and requested same day delivery. As always MightApe delivered the item within the closure of the day. I already use it in a MAC PC and it was pretty much plug and play, I had to use an adapter for the thunderbolt port in my laptop as MAC model I have does not support USB, but that is another subject. Laser pointer works ok in an Epson Projector, However, this pointer is a no no if you are going to use in a very bright TV like projector, the monitor brightness nullify the pointer. As a slide changer it does its job, provided you don’t need to stay to far away from your laptop. I tested till 10 meters away ish, and you can tell that the pointer response is delayed when reaching the 10 meters mark.
