Awesome Product

I've had this for a few months now, and it's perfect!! It's definitely worth the money, it's very easy to set up (all you quite literally have to do is just plug it in!), and the functionality is really good. There's no additional software you have to install or any crazyness. Plug it in, and boom, it works! The bluetooth connectivity is really strong and good. 100% recommend buying this!!

A little disappointing

UPDATE 2 - 7/8/21So 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 UpdateUPDATE - 7/13/2020So, 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 ReviewI 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 functionalSo 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.

This product is for a Bluetooth headset/mouse/keyboard if the PC does not give Bluetooth access

It works great with my headset I would think this is perfect for Work from home folks that is using a work provided PC that has Bluetooth restrictions

Easy install, much cheaper than Bluetooth hardware replacement

I have a Lenovo Yoga laptop I bought in 2020 for college that has been nothing but a headache. Recently, the Bluetooth hardware completely failed and it would’ve required an extensive (and expensive) repair to get the hardware replaced. I use Bluetooth headphones to attend class lectures, and the laptop would’ve required another adapter to add an aux port to even try to use wired headphones.This little USB gadget fixed my problem for $10. Install was quick, easy, and done in about 5 minutes. I was concerned this would require some 3rd party Bluetooth menu to connect, but my laptop recognizes this adapter as a native Bluetooth drive, with all settings available via the same menu as before. The only small snag I had was that my Bluetooth devices wouldn’t connect until I removed and re-paired them in the settings menu, but they reconnected on the first try and now work flawlessly.You’ll need the model and version number to find the right driver to install. You can find the model number on your product packaging or this product listing under the “Product Specifications” section. The version number is printed on the bottom of the USB adapter itself.
