I bought my first Logitech R800 in 2012 (after years of using the R400) and have been using it constantly ever since. I'm a professional teacher, teaching 8-10 hours a day, 6 days for about 30 weeks a year (courses averaging over 200 slides a day). The R800 I currently own has changed slides for me over 200,000 times (no kidding) and shone its laser for hours on end over the years. Just this week (08/08/2016) the buttons started to wear out - I have to press the button 2, 3 or 4 times to change the slide. I've just bought another R800 without hesitation (and was VERY happy to see they're still available). In my opinion this is a fantastic high quality tool that does exactly what it was designed to do. It switches slides back and forth seamlessly. The green laser pointer is very bright (much better than the red laser R400). It is comfortable to hold and fits easily in a pocket. You can delete your slides with a simple click. I just couldn't ask for more from a remote moderator type tool. Note. I don't use a timer on the device so I can't comment on this feature. ' Capitan, and even a few times on Linux systems. I've never had a problem or had to make any special adjustments. Just plug it in and it works. I am very happy with it. Actually I'm wondering if it was worth it for me to buy two today to have a spare in case they stop producing it? Hope that helps.
