Amazon Customer: 1. The "drivers" for this device are malware. They include a keystroke monitor (for grabbing usernames and passwords) and they also mine your drive for any PIO and send it back to China.
2. The computer that I installed this on suddenly took a performance nosedive after the driver was installed. The drivers ran all the time and liked to increase the memory used until the system locked - either malware or a bad memory leak.
3. It couldn't connect to any of my bluetooth devices - not my speakers, headphone or earbuds. It wanted to connect to my phone via bluetooth, I guess to complete the data mining and other malicious tasks on the phone too.
4. There is no technical support of any kind. It is not "plug and play" as advertised. The card says to go to a website and use an involved process to install the "driver"

Conclusion - The driver for this device wanted full access to everything on the computer - and that's a characteristic of malware used for identity and credit theft. The goal of the seller seems to be to get your id's, accounts and passwords plus any other information and send it back to the mothership, and it just doesn't work properly.

Coinsuer: I received this product in the mail today and it works fantastically. It isn't quite plug and play like the package described, however once the drivers are installed, it easily finds Bluetooth devices and pairs them with your computer. I used this for a keyboard - which I am typing on right now - and it works with no noticeable delay.
Great product and fairly cheap, if you need Bluetooth or a stronger Bluetooth single, this product works great.

Jessica Jones: I own a Bose Speaker Soundlink Mobile II. I've had it for about five or six years. It is Bluetooth 2.0, I think....Anyways, it has been paired all that time with my old laptop. I recently got a new laptop with Bluetooth 4.0 and, of course, even though the speaker works perfectly with older devices and even though it cost a ton of money, it wasn't pairing at all with my laptop. After searching the internet for Bose updates (that would NEVER download), and re-trying, restarting, pushing and holding various buttons down for ten seconds in various configurations, I was soon at my wits end. Then I read a non-Bose employee suggestion to buy a CSR dongle. I had no idea what it was (and still don't, really), but I ordered it anyway, because it was only $6.50. Some reviewers said that it was a piece of junk and that it never connected their devices. Most said it totally saved their lives. If you fall into the first category, let me tell you what to do (Because...for some reason, there are NO directions, so I can see why a person would be angry!!!)
1. Open the package and insert the small cd into your pc drive. (If you don't have a cd drive, don't buy this one. Instead, look for a dongle...

Logan Edwards: First off, the package was delivered a week before it was supposed to, which is fantastic to begin with! The product itself is exactly as you'd expect, looks similar to a wireless receiver for a mouse or keyboard. The packaging was easy to open, simply a friction-sealing plastic cover, which gives access to the product along with a 2 page pamphlet. Inside the pamphlet they even included a small driver disc for you Windows 7 users out there! Considering the shipping was free, I got it sooner than expected, there was a driver disk, and the packaging was more than high enough quality, I am very satisfied to give the product an all around 5 star. The bluetooth menu pops up in your toolbox immediately without any need for driver installation in Windows 10, and the advertised 33 foot range is accurate. To test this, I used my AirPods, which have a 35 foot range. I set my phone on my desk, and walked with the AirPods in roughly 40 feet across the house before it cut the signal. I then tried the same, but with a video playing from my computer, and the signal cut at the same spot for both of them. Very satisfied!

Tl;dr - Great product, plug and play for Windows 10, the advertised...
