I had the pleasure use the not so new Logitech Spotlight today, I´ve previously used Logitech R400 and R800 with great success. So when I had the chance today I was positively surprised.

The Logitech Spotlight lets you navigate slides from up to 100 ft (30 meters) away and use the advanced pointer to Highlight, Magnify, or pinpoint areas of focus with a Digital Laser. Download the desktop application from Logitech and you can decide the setup of the pointer. From the above mentioned pointer, highlighter and magnifyer, you can set up a timer (the pointer vibrates) as well as the usual flip in presentations slide.

Use the on-screen cursor to play and pause videos and open links. Spotlight connects instantly via the Logitech USB receiver or alternatively bluetooth.
As mentioned above manage your time perfectly from your first until your final slide. Set timed milestones within the logitech application and receive vibration alerts directly to hand.
The logitech Spotlight is univerally compatible and works on Windows and Mac platforms, and on Powerpoint, Keynote, PDF, Google Slide and Prezi presentations.
A full charge lasts for 3 months.
