  a bluetooth key for a PC that doesn't have one?

  blue tooth key bought to be able to connect the computer to the internet via a mobile data access point on a telephone, alas, it doesn't work like that, .... the computer can provide access but not fetch internet access. probably not a problem with the key itself but with the clarity of the information provided by the manufacturers.
  
  You'd better be a good IT specialist to understand how to configure this thing; you need internet access to update the bios (!) and only then will you be able to see it in your settings.

  Efficient!

  This key does the job perfectly. Thanks for the good advice LDLC! Received the package quickly. Works immediately with Linux (Ubuntu) on both my laptop and my Dell tower. Just plug in and BT works, no driver installation required. Top

  Compliant and efficient equipment

  I bought this to connect bluetooth headphones, no delay between the sound and the image on my fixed computer and a satisfactory range!
  I didn't give it 5 stars because at first I installed the software on the CD supplied with the hardware and the connection with my bluetooth headphones was abominable (sound completely chopped up every 1.5 seconds, horrible quality). I thought that the hardware was defective or that the problem came from my headphones but no, the problem came from the software, as soon as I uninstalled it, my headphones worked perfectly, rather surprising...

  does not work

  Doesn't work properly, I can't get distinct sound with it, and the images are pixelated. In short, I can't use it.

  Does not install on a Windows 10/64 bit computer

  I can't use it on my computer running Windows 10 64 bits.
  The box that displays Win 10 Support is misleading, the internal documentation clearly states "Win 7, 8 and XP: a shot in the dark!

  I ordered this dongle to go with a wireless headset. The range is about 10 meters, which is enough for home use.

  Works well under Linux. Connection (headset and phone) impossible after a few months of use but "solved" by unplugging and replugging the bluetooth adapter.

  Good, but...

  Directly throw away the supplied cd, whose content is not compatible with Windows10. I had to uninstall it and restart my computer to make it work, well... That's the last straw.

  This is good but

  The main problem with the product is the Bluetooth distance.
  -1m = good quality with occasional crackling
  1m = recurrent crackling
  1m20 = untimely crackling or even disconnection
  1m50 = no connection
  I'm a bit disappointed because the whole point was to have my Bluetooth headset and walk around my house, or at least in my room, but no.

  in reply to BAT-signal
  I have been using this dongle for 3 months. Connected to a CM "AsRock Fatal1ty X99 Professional 3.1", with Win 10 64 bits. Installed in 2 minutes, immediately recognized by windows and all my devices, including my mobile.
  I recommend this dongle.

  No problems for the installation of the key
  However, if you proceed with the installation with the DVD, an error occurs with Windows 10, so you have to review what the DVD installs as a driver that hinders Windows

  Works great for all your Bluetooth needs.
  I had to download the necessary Bluetooth driver, but other than that it works like a charm. I use it to sync with my Bluetooth speakers and there is no lag.

  Works well on raspberry

  Great delivery from LDLC, as usual.
  
  I bought this key to stream sound from my Android phone to a first model raspberry (audio sink A2P). The USB key is recognized without any problem (drivers present in the Linux kernel, nothing special to do). After a lot of fiddling with the alsa and bluetooth programs of raspbian buster, I got what I needed.
  
  Note that I use this key with another one (USB N10 Nano from Asus). They work simultaneously without problem (I was afraid of signal interference).
  
  In short, I am satisfied!

  Perfect for Linux Ubuntu 18.04

  This bluetooth key works perfectly on a machine with Linux Ubuntu 18.04. My goal is to broadcast music from the PC to a bluetooth enabled stereo. It was enough to connect this key then to detect the hifi system in the interface proposed by Ubuntu: 2 minutes maximum. I therefore consider that it is plug and play. I did not need to install any additional driver. Similarly, I did not need to modify any Ubuntu configuration file. The Ubuntu 18.04 kernel obviously already has the right driver. Really good!

  Running on the fully updated Windows 10, it almost instantly recognised all the Bluetooth devices in the house.
  It is used in the home.
  As recommended in the installation of the product, it is necessary to remove the other Bluetooth software(s) beforehand.

  Discreet and functional

  I plugged it into a USB 3.0 port on the front of my tower and it worked. To do this properly I had to download the driver for Windows 10 - 64 bit as far as I was concerned.
  
  Adding a wireless device: in Win10 right click on the Start menu > Settings > Devices, Bluetooth and others > Add a Bluetooth device.
  
  My Sennheiser 450 wireless headset was recognized perfectly.
  
  Important note: this USB to Bluetooth adapter does not do Wifi.

  Discrete

  A small connector to pair all these devices with bluetooth, just lacks the latest standards, but this key will already do the job properly.
  Attention however, the passage by the cd of driver will be obligatory.

  One star, because it does not work on Windows 10 64 bits pro. Despite many unsuccessful attempts, install, uninstall, update the driver, nothing happens.

  Noice

  Shipped on time and without hassle.
  Used to connect a ps4 dualshock 4 controller to a fixed PC, it works very well you just need to install the dongle, plug in and then press and hold share+ps4 after activating bluetooth (about 10/15 sec I would say) you should be listed under the name wireless controller. If you are under W10 everything is casi-auto otherwise you will have to install drivers to solve the problems if you have any.

  Good product

  The product does what it is asked to do, it is plug n play, no need to install any driver, I just take away two stars because it is a bit expensive for my taste for a simple bluetooth dongle, at this price it could have done Wi-Fi, even if it means adding a little bit of length.

  Not satisfied with this product, even though it is an Asus brand and not unknown.

  If W10 recognizes and installs the product without worry (generic driver), there are too many untimely disconnections although, with my earphones, I am 50 cms from the bluetooth dongle. I've been using it for a while now, but it's not working as well as it should. Very disappointed.

  Just perfect

  My PC has a built-in Bluetooth card but it didn't recognise my Bose headset. I plugged in the USB-BT400 Bluetooth dongle, Win 10 updated the driver by itself, I rebooted and it works perfectly. As soon as I turn on the headset, it takes over and no more sound on the speakers... Too TOP.

  Windows 10: DO NOT install the driver CD!

  (Win10 64bits) Stupidly, the first time, I installed the CD provided with the dongle. It worked... yes, ONCE!
  Then crap, no connection, or no sound, or distorted sound.... Tried to reinstall or repair, looked for a driver etc..
  FINALLY: fired everything (Device Manager AND WIDCOMM), cleaned up.
  Then simply re-inserted the thing into USB: Win did the job by itself, and now all is well.

  Meets expectations

  This adapter works as intended and is easy to install. It also has the advantage of being tiny.
  
  However, my speakers could not be detected on both desktop and laptop computers and I was forced to connect them via a jack cable. However, this problem seems to be related to certain types of speakers and not to the adapter.

  Efficient and space-saving.

  So unobtrusive that I've already lost the thing.
  It's a pity because it seemed to do its job, not really with a contest speed but very honestly and without too many disconnections even in a workshop cluttered with various network obstacles.
  Correct throughput and low price, recognized without problems and without software under Seven 64.
