Does exactly what it says on the tin. Very competent device. Be aware that the "Start Presentation" and "Blank Screen" buttons don't work on Mac OSX and Keynote.

Our faculty love this product for classroom teaching. It works well with multiple platforms and operating systems. We recommend it.

I went to a store to "check out" various brands and I am well pleased with my selection of the Logitech R400. It fits in the hand very well, easy to use and is concealed from the general audience when presenting programs. The carrying bag is an extra bonus and fits nicely in a laptop case. .

I am a female consultant trainer and use a MacBook Air. This Logitech pointer replaced a 20 year old Logitech that a student broke. This new Logitech model has a better feel than the original clicker. It has a comfortable ergonomic fit, is lightweight for travel and works with my MacBook Air.

This is the kind of presenter I was wanting for a long time. The size is really pretty good. I like the colour which doesn't distract the audience. Easy to handle and works seamlessly.

Compact

Very good genuine product come in a very nice packet and comes with a poach so that we can store it nicely when we don use it. No regrets for buying.

Delivery was super fast. It does its job. I have also used it before, quite like it. The particular piece I got was not the best one hence removing 1 star. The battery cover and the usb are very loosely attached, they come off very easily.

Don't get these if you want to use it with a LED display, you wont see anything since the "laser" is super weak.

works great on prjectors

fails miserably on LED TVs (not surprised

I kept borrowing one from a friend and finally had to have one for myself. I have used this kind of presenter for a long time and it works great!

For presentations or showing videos, it's great. But it is not a full function remote mouse replacement.

Simple, efficient, affordable; Just plug in the USB key that comes embedded in the device; Has a red laser pointer as well; Buttons for left and right arrows, blanking screen, and for starting video; Not fancy, but basically what you need

Left and right arrow buttons do not seem to be programmable to work with, say, up and down buttons; That would be nice for some applications
