TP-Link USB Bluetooth Adapter for PC (UB400), Bluetooth 4.0 Dongle Receiver Support Windows 10/8.1/8/7/XP for Desktop, Laptop, Mouse, Keyboard, Printers, Headsets, Speakers, PS4/Xbox controllers

After many problems and days of setting up the device, I can confirm that I do not recommend using this technology, it is complicated to use if your device is not compatible and it causes more problems than benefits if from the start you can't use it as it should be, for example: turn on your device and pair it and ready to use, if these steps can't be done the first time, be prepared to a series of problems where you may never be able to pair your device. I am dedicated to computing but I had never used this bluetooth technology, now that I am I have started I have been able to see the whole series of problems it generates if you find any problem I bought 3 bluetooth receiver devices to compare brands and learn how easy and comfortable it would be to use this technology and in the end I can conclude that I would not recommend it to the average user who does not know much about computers because if he has a problem he will not know how to solve it. I had several problems, it was tested under windows 7 and 10 latest versions to date sept 2019 , the process was to install drivers for windows 7, be careful not to connect it to a usb 3 port otherwise you will have problems (it will not be told to you), the second is to see how certain devices can be linked to your receiver and others will not be able to, the worst thing is that if you change the port of the receiver, you will not be able to connect your devices that you had already linked and the worst is that you have to return to the port where you them had saved, delete them and now if you connect your receiver to the new usb port and re-parent them (took me a long time to find out) the same thing happened in Windows 10. Now the worst case is that if you have a laptop with bluetooth and you have all your devices paired but for some reason it broke down and you chose to buy a new receiver you have the same problem that you won't be able to pair your devices because they have to be erased from the vIejo receiver to be able to link them with the new one, this is the big problem that this technology has. It may be a Windows problem, but in version 7 and 10 it is the same. In the worst case, you must uninstall the drivers of the bluetooth receivers you have installed to be able to use a new one, otherwise there will be conflicts and you will only have to format your pc to be able to use them correctly of your new bluetooth receiver. once you got through the hell of the setup in case you had any trouble thats not very good i wanted to hook up a ps4 control and it CANNOT and some newly acquired sony headphones , the headphones had an audio delay of up to 2 seconds which is attributable to the receiver because as I said at the beginning I tried other receivers and with these I did not have so many audio touch-ups , but you need to confirm i had to do clean installs of windows because when installing the driver for 2 receivers on the same pc i didn't do it could be related to hearing aids or command, how is it was in conflict. Regarding the transmission distance it is only 9 meters, at 10 it is no longer possible to sarlo correctly, they start the mute and the control did not work well, with the slightest object that was in the way you stopped hearing sound and audio delay has com started, honestly the bluetooth technology leaves a lot to be desired as they are version 4 and i thought they had improved, i had a version 1 receiver and decided to buy the newer one thinking that they had improved but I think it's the same, I wouldn't recommend spending money on devices with this technology which has little compatibility and gives a lot of problems. i wanted something wireless i ended up putting in a usb extender and getting my hearing aids receiver as close as possible to about a meter because if you walk away the audio delay starts and until you restart hearing aids it is dialed, if a person passes by at this time you will lose audio for a moment or if you move away 5 meters the audio delay will start and it does not dial, this is only noticeable in games video, if you listen to the music it's notI think you realize.
