Pros: - Works very well with my Sentry bluetooth speaker from across the room (15 feet or so)
- Works okay-ish with my PS4 controller (more on that below)
- Drivers were easy to deal with

Cons: - PS4 controller connection flaky at times from less than 5 feet away
- First one broke when I removed it from the USB port (but was replaced free of charge, of course)
- Has a blue LED... that only shines INSIDE the USB port, making it fairly invisible (can be a pro for someone who likes that sort of thing)

Other Thoughts: ASUS has really stellar customer service. I was contacted the day after I filed for RMA and given a shipping label immediately. The new dongle came in ~a week and a half later.
More on that PS4 controller connectivity, I'd like to note that the controller is is very good condition and works with my PS4 perfectly. However, from 5 or so feet away from my laptop, the connection is flaky. I have noticed that removing any interference (body parts, stacks of books, papers) from between the controller and receiver fixed the issue. For me, this isn't a deal breaker. For someone else with their computer under their desk this may be an issue (although getting a cheap USB extender is an option.
The LED I mentioned earlier is an oddity for me. Why include an LED and make it hardly visible? Why neglect to mention this in the product description? It doesn't really affect the usage of the receiver in any way to my knowledge. To be clear, the LED is barely noticeable and I didn't see it until ~2 weeks after I got it.

Pros: fit good

Cons: none

Other Thoughts: yes

Pros: Have a Razer Orochi Bluetooth mice and my laptop does not have bluetooth, plugged this in, win10 automatically installed the driver, and it is getting very stable reception about 5 feet away when I am doing presentations.

Cons: no cons so far. After MIR, this is very high quality product for the price.

Pros: works great with win10x64 and jbl-j56bt headphones
NO SOFTWARE INSTALL NEEDED, plugged it in and it connected to headphones first try

Cons: couldn't get it to work with win7x64 with or without software

Other Thoughts: going to get another one for my other comp now, deleted my one star review (nice option Newegg,thank you)
Always the Egg

Pros: work right out of package

Cons: none

Pros: Great value for the money and worked.

Cons: The only con that I can think of is that you have to download the latest driver from the Asus website, but honestly that is installation 101.

Other Thoughts: My primary use of this device was to transfer files back and forth between a computer and a smartphone. I did not use or test any of the other Bluetooth functionality.

I had purchased a more expensive brand of Bluetooth adapter by Kensington, and every time I tried to select the files to transfer, it hosed my Windows Explorer.

The only surprise I had with this BT adapter was that the file transfer did not see JPG files which is how my pictures are stored after the initial install. However, applying the latest driver update fixed this issue. I did not count off for that because I consider this step part of a standard installation.

Pros: I purchased this to use with my bluetooth PS3 controller to play PC games from my couch & tv. It works perfectly.

Cons: None

Other Thoughts: Would purchase again.

Pros: - FREE!!!

Cons: - FREE!!!

Pros: - works
- ok range (10M?)
- small

Cons: - ? can't really think of any

Other Thoughts: It just works. Using on Windows 10 machine.

Pros: Plug and play on El Capitan

Cons: Range is absolutely terrible. Signal completely cuts out less than 1M (3 feet) away. Tried multiple BT headsets, all works perfectly except with this BT dongle.
