I needed this device to connect my cell phone directly to the desktop without the need to use a cable. Works very well and no more hassle of plugging in every time.
I have a USB multi-port device that I can now leave the adapter plugged in at all times. Transfer speed is no problem when sending pictures from the phone to the desktop picture album.

The TP-Link USB Bluetooth Adapter for PC is a true game-changer when it comes to expanding connectivity options for your computer. This tiny dongle has made a significant impact on my PC experience, and I'm thrilled to share a positive review.

First and foremost, the plug-and-play functionality is a huge plus. The setup couldn't be simpler; just plug it into a USB port, and it's ready to go. There's no need for additional drivers or complicated configurations, which is fantastic for those of us who value simplicity and convenience.

The compact, nano-sized design of this Bluetooth adapter is impressive. It's so small that it doesn't protrude from the USB port, making it a sleek and unobtrusive addition to my computer. It's perfect for laptops and desktops alike, and you can leave it plugged in without worrying about it getting in the way.

The Bluetooth 4.0 technology ensures fast and reliable connections. Whether I'm connecting wireless headphones, a keyboard, a mouse, or any other Bluetooth-enabled device, the adapter handles it all with ease. The range and stability of the connections have been exceptional.

Furthermore, the TP-Link brand is synonymous with quality and reliability, and this Bluetooth adapter is no exception. I have confidence that it will continue to perform flawlessly over time.

The TP-Link USB Bluetooth Adapter for PC is a must-have accessory for anyone looking to add Bluetooth connectivity to their computer. Its ease of use, compact design, and reliable performance make it a valuable addition to any tech setup. Whether you need it for work, gaming, or entertainment, this dongle delivers on all fronts and has greatly improved my PC experience. Highly recommended!

A little disappointing

Reviewed in the United States on January 21, 2020

Color: BlackVerified Purchase

UPDATE 2 - 7/8/21

So in the time since I originally wrote this review (and it's update) I have found this adapter can work quite well and some of my early experiences with it were probably due to the limitations of Windows 7.

One very key discovery I made is that if you just stick this into a USB port on the back of your PC, you will get OK reception if you're close but you'll get very spotty connections from any distance at all (and might even get dropouts from as close as across the room the PC is actually in).

What I have done is used a USB extension cable and mounted it high on the wall (not the prettiest thing in the world but it works wonders for the range). Once that was done, I was definitely getting more range and a much more reliable connection throughout my apartment.

It's not Bluetooth 5.0 but it's not bad for the price. I was looking to upgrade to Bluetooth 5.0 recently but most of the 5.0 dongles they have on here have mixed reviews so I ordered another one of these as a spare.

END Update

UPDATE - 7/13/2020

So, I originally found the Windows 7 driver that I downloaded that is supposed to work with this adapter installs and appears to work on Windows 7 but I could not get it to work with anything I tried (This adapter is plug and play with Windows 8.1)

Eventually, I uninstalled the driver, went into Device Manager and clicked for it to scan for hardware changes. So it found the adapter and (of course) displayed the error triangle that told me there was no installed driver for it and THEN it went online and found a driver for it and installed it and now it works with Windows 7 as it should. So if you have Windows 7, I recommend you try that BEFORE you bother with the driver they tell you to download for it. It's much simpler and it actually works with my system and doesn't require installing anything extra.

END UPDATE
--------
Original Review

I bought this for my Windows 7 PC on the promise of a driver download that would make it compatible. So I downloaded the driver and found it to be very confusing and barely functional

So I tried it on a Windows 8.1 PC and it was plug and play (as it's supposed to be). I guess it's fine for Windows 8 and up. If you have Windows 7, expect to have to fight with it to make it work.

I have also had an issue with low volume on Bluetooth devices I'm sending audio to with this adapter but I'm not sure I can blame it entirely on the adapter so I'll leave it at that. For example, I have a stereo that has built-in Bluetooth and I can barely hear some Youtube videos with full volume on my PC and the stereo. That stereo goes plenty loud if you're using the radio or the CD. Turned up all the way it should be louder and just isn't. Maybe it's something I'm doing wrong but if it is, it isn't obvious.

Purchased this to replace the bluetooth adaptor that came standard on the Silhouette Cameo 4 which is absolutely terrible.
Plugged it in, forgot the old bluetooth connection on Windows 11 and re-added the machine.
It is now running perfectly stable over bluetooth.
