Setting it up was a breeze; it seamlessly integrated with my desktop computer, instantly recognizing my Bluetooth headphones and other devices. The improved connectivity has not only decluttered my workspace by eliminating the need for cumbersome cables but has also given me the freedom to move around while staying connected.

Plug and play
Adds wifi and bluetooth to devices that don't have it from the factory. Seems to work just fine. I did end up having to use a wired internet connection on my garage pc I use for indoor cycling, which I suspect was due to conflicting signals.

Simple and works straight away
Simple and works straight away This Bluetooth adapter worked really well for me with no fuss at all. I plugged it in and it worked straight out of the box, with no drivers needed and no messing around with settings. I’ve had no issues connecting any devices so far and everything has stayed stable once paired. It’s small, discreet, and does exactly what it’s meant to do, which is all you really want from something like this.

Brillaint, works as intended
Why did you choose this product over others?: I trust TP Link as a brand for their reliabilty and functionality. As the intended use was for a laptop, the nano sizing was descrete enough to leave plugged in the laptop without looking out of place and without being too big that it didn't get knocked and broken. Ease of installation: Simply plug in and download driver. Was simple and only took a few minutes to install. Speed: The network speed of the laptop was rubbish being an older style laptop now with this plugged in getting download speeds around the 400mbps with 150mbps upload.

Exactly what I needed after failling everything
Since recent Windows updates, my laptop's Wi-Fi and Bluetooth drivers annoyingly disappeared one by one. With limited USB ports, I needed a 2-in-1 dongle offering both Wi-Fi and Bluetooth in a single, compact unit. As mentioned in other reviews, installing the Bluetooth driver was the only hurdle. The Wi-Fi driver installed automatically upon plugging in the dongle. However, for Bluetooth, you need to manually run 'autorun.exe' from the included mini disc. Unfortunately, my laptop, like most these days, lacks a DVD drive. I had to borrow my husband's desktop computer to access the disc's content and transfer it to my laptop for driver installation. Thankfully, it worked! Overall, I'm pleased with the TP-Link dongle. While it might be pricier than some Chinese alternatives on Amazon, it delivers reliable performance. My work-from-home routine primarily involves using MS Office and other applications, so speed isn't a major concern – stability is key. This dongle fits the bill perfectly. I highly recommend this product for anyone seeking a dependable 2-in-1 dongle with dual functionality.

Regularly disconnects
Was looking for a wifi dongle for back of PC tower. Fits well and connects. But, the connection often decides to randomly disconnect and then reconnect whilst I'm trying to do something in my browser. It will eventually reconnect but this is a 5-10min affair of not being able to work. Had to buy a second dongle.
