Excerpt: Simple, no software to install, and the batteries come installed in the unit. It's pretty self-explanatory - we use it to advance PowerPoint slides in our church services. The range is longer than expected, and not having line-of-sight is has not been an issue. We get ranges of 40+ feet and haven't missed a slide since installed.
Excerpt: Use this product with a mac mini running mavericks and I have not experienced any problems. I plugged it in and right away was able to use it with powerpoint. Great product. Batteries are needed for the remote, but they were included in the package.
