Pros: This just works. Tested on Windows, Linux, and Chromebook with Google Slides. Both Forward and Backward buttons work, but the Screen Blank feature doesn't work with Google Slides.

The USB Dongle tucks away conveniently.

Cons: The USB dongle is huge. In 2016 I have become accustomed to small USB devices, but this one sticks out nearly 2 inches for maximum breakbility. I really hope it doesn't snap off in my laptop.

The laser pointer is the weakest and smallest dot I've ever seen. I may have to continue to use a separate laser pointer.

Other Thoughts: For those with small hands this is probably a great device, but I have very large hands making it a bit awkward to hold. Fortunately it is heavy enough with a rubberized texture to give it a nice feel.

Pros: I'm a teacher and I move around the classroom quite a bit. This presenter does not loose signal at all. Even comes with a very convenient place to store the dongle.

Cons: None yet.

Pros: Works great (for >5 years)
Easy to see the red
Rapid interface with any computer

Cons: Some people like green lasers?

Pros: Works with most ubuntu distros and windows computers.

Cons: The windows computer I tried it on wasn't hooked up to the internet so it didn't work until I put it online and did some updates.
Couldn't get it to work on xubuntu.

Other Thoughts: I was very happy with this, it works on both windows and linux. It also works with both MS PowerPoint and libreoffice with no difference between the two. The only thing that doesn't seem to work is the packaging says that you can start a slide show by pressing the laser pointer button, which doesn't work.

Pros: Easy to hold and control. Has been my go-to for teaching a week long class every other month.

Cons: None

Pros: size, ease of use

Cons: 2 didn't last

Other Thoughts: I have had 2 and neither lasted for even a year. I bought the second one thinking it was fluke that the first broke but it lasted only 4 or 5 months too. I don't use them that often so felt they should have lasted, with batteries removed so they didn't corrode, for longer

Pros: Advances slides as expected.
Works with LibreOffice as well as PowerPoint.

Cons: Weak laser.

Other Thoughts: I had to replace my previous one because the receiver disappeared. The laser of the new one, same model as the old, is hard to see in a classroom. Previous one was noticeably brighter.

Pros: Great buy with fast shipping.

Cons: None

Pros: Connector Storage within handheld - less chance of losing it
Signal Range

Cons: None so far

Pros: Very comfortable, easy to setup and use with windows. Large, but not cumbersome it's actually quite light even with batteries installed. I think the size actually helps to keep it from getting lost or misplaced. There is also a neat feature that enables you to store the wireless receiver in the main device so you won't lose it while travelling.

Cons: It is quite larger then your usual laser pointer.
