Excerpt: The R400 has a much improved design for storing the receiver, and it seamlessly integrated with my Surface Pro/Windows 8 (no setup or software to load). The built-in laser pointer is also a nice feature.
Excerpt: Decent product, connects to PC easy. Would be nice if turn on switch was activated when USB remote was removed. When placing USB dongle back in must remember to turn off switch. Nice button to start presentation.
Summary: Normally, logitech devices are easy to use and handy. This one is also easy to use, small and portable. But one thing it doesn't have that disappointed me was the click button. One cannot play a video or music from a distance with this one.
Summary: If you're looking for a remote just for starting a slideshow and going backward and forward, this does the job. It has a nice feel, although sometimes the buttons aren't as responsive as I'd like them to be when standing in front of a room full of people.
Summary: I bought one of these 2 years ago and I just loved it. I got another one for work and the one I got this time is of slightly worse quality. The plastic used just seems cheaper and the gaps between the buttons are irregular. Despite that it works just fine and does what it should.
Summary: Perhaps it's just me, but I found that the on-off button (the one on the top, not the one on the side) often got stuck in the "on" position. Getting it unstuck was distracting me from my lecture, so I simply switched to a different pointer that did not have this problem.
Summary: Everything works fine with this presenter and it seems to be well built. The only thing that is realy flimsy is the on/off switch. It works, but sometimes doesn't seem to slide all the way to the on-position and gets stuck halfway.
