I dont regret buying

I bought it for the apps ability to flip through slides on keynote AND powerpoint. However, I quickly learned that you can also use it as a TRACKPAD!!! So for .99 this is definitely worth it. The official keynote remote app may look cooler and even can preview what the next slides are but a)doesnt work with anything other than keynote, which is fine if thats what youre looking for b)its much more expensive.
Yes, you have to download an app(for free) on their website but thats what makes it secured to your personal computer. Once thats done forget ever having to get up out of your chair. This really impresses lots of my friends, including my friend who works for apple. Enjoy!
