INFINITER LR8 4-in-1 Function Wireless Presenter with Media Player Control, Wireless Mouse, Red Laser Pointer, and 2.4 GHz USB Presenter (Powered by 1 AAA battery, Included!) Works Great for PowerPoint on Windows Operating Systems

This device works really well. The only slight problem is that it does use rather cheap material, which can break quite easily. This showed up when I damaged the wifi transmitter after having it in my pocket. I managed to tape it back together again & it still works.

Easy to use laser pointer that effectively controls PowerPoint and Keynote presentations away from the keyboard. Just lift and pull out wireless USB receiver from end of pointer then plug in port to start. Couldn't be easier.

ABSOLUTE RUBBISHDO NOT BUY !Stopped working after a month - flimsy and poor quality for the money

Reliable and compact

The INFINITER LR8 arrived much sooner than I expected, and after opening the packaging I was very impressed with its sleek black design and how little it weighed. I was also surprised to find that the packaging contained the required battery, which meant I was able to start using the INFINITER immediately, without having to search for an appropriate battery.Initially I was confused by all of the buttons on the INFINITER, however after reading the very easy to understand users manual I realised it was very simple to use. After mastering the functionality I found it very simple to connect to my Mac, and it worked seamlessly with my chosen presentation.The only downside was that I found using the drawing function difficult even though the instructions seemed very comprehensive.Overall I am pleased with the INFINITER and I would defiantly recommend it to family or friends.

I was really impressed with this laser pointer/presenter, and I would definitely recommend it. Initially, it seems like it is quite expensive for what it is, but this is actually a really capable presenter that works on Mac and PC. It has several features, and it is great to use.I found the built-in USB receiver really useful, as it prevents you from losing it. The receiver was quite hard to remove from the main unit, but this is a minor issue. Many presenters have separate receiver which can easily get lost.The presenter can go to the next slide, previous slide, put on a black screen, and end show. It worked great for me on PowerPoint on Windows, and Keynote and PowerPoint on Mac. I like the shape of the unit, as it is quite small, but packs a lot of functionality.A slider on the side allows you to switch between three modes: Presenter, Mouse, and Media Player. The presenter works as you would expect, the mouse mode allows you to move a mouse around the screen using the keys on the presenter (this is quite clumsy, but it works), and click using the enter key. The media player mode controls the volume, skip tracks, and pause/play the media. All three modes for well, but I only really used the presenter mode.The laser is also quite an important part of the functionality here, and it worked really well. The red laser was bright and, more importantly, visible on a screen. The laser button is well placed, so it’s unlikely that you will knock it when trying to navigate a presentation.Overall,whilst this is certainly not a cheap presenter, it works really well. I would definitely recommend it for making your presentations better. The long battery life was really good, especially as you can just swap out the battery when it runs out.I was sent this laser pen for review. The opinions expressed here are not effected by this.
