    Here's my review after 15 days of extensive usage. So here's my initial impressions when I first opened the box and found this tiny device in it. On device, it had Tp-link branding on a side and Bluetooth written on the another side (Pic attached for your reference) and some paperwork.What was my purpose for buying this product?I own a Desktop which is almost 8 years old and it doesn't have inbuilt Bluetooth. I wanted to connect my Mi Sports Bluetooth Earphones to my Computer which was not possible. So I searched for some products stating "Bluetooth for PC" and I found this.I read the ratings & reviews and was quite impressed by it and went ahead to buy this one. So now lets begin with some pros and cons.Pros:- Easy to install, Just plug into your USB port and it starts working.- Superb sound quality, No sound drops as such from my Bluetooth earphones- Very tiny and handyOnly 1 Con:- Whenever I move away from my computer, I experience certain sound drops despite of being in a same room.Firstly I thought its a manufacturing defect that's why replaced with a new one but the problem still resist.Conclusion:I am using this product for almost 15 days and I am really impressed by the quality TP- Link has provided with less than 500/- Rs which is quite remarkable. This is the best product in its segment and no competition for it whatsoever. I would surely recommend to go with this product if your PC/ Laptop doesn't have inbuilt Bluetooth. You can connect any device which has Bluetooth for eg. Phone, Bluetooth Speaker, Bluetooth earphones, etc. You can also transfer/receive files using this Bluetooth device.It was my first attempt to write a review. Hope you like it. Thank you.
    This review is for "Bluetooth 4.0 Nano USB Adapter UB400"Before this I bought a cheap Generic CSR 4.0 Bluetooth adaptor from Amazon and it's connection was barely stable. So I return that and bought this one. Sure, it's not as cheap as some other options available but it is stable and the connection is quick.So, pros and cons.PROS-- Easy to install. Just plug and play.- Windows 10, 8 and 7 compatible. Win7 needs driver.- Quick connection and Stable.- No laggy sound.- Small size- Good range. I plugged it on the back of my CPU which is inside a wooden box frame. Still works fine- No LED. Pros for me- 1 year warrantyCONS- I think the price could be less.- There is a negligible latency.- No driver disk included for windows 7. Need to be downloaded.------------------In case you are wondering, the MRP on my box is ₹699
    This is one useless device and lets me tell you why1. With the Win 10 2004 update, it won't be auto-detected. You need to download CSR harmony driver which is 460MB in size. I had a 10 year old BT dongle that took 5 MBs of space and performed flawlessly until one day it decided to hang up the boots.2. The interface is childish and seems to be designed by someone who had no UX/UI experience. If you add a device and that device is turned off and powered on again, there is no way in hell to make this dongle get to connect to that device again other than to remove and add that device again. At times, this dongle will automatically detect the device, but if you add two devices or more, this will act like 'none of my business' and you will end up scratching your head what the heck happened.3. In some applications, parallel existence of Stereo and AG audio is not supported. You need to disable one of the two options for your bluetooth audio device in order to hear them. What a dumb choice of options.Pros:Sound quality is ok, not too bad like those Chinese ones. That's it.Avoid this altogether unless TP Link fixes above issue with an update.
    This bluetooth adapter from TP-Link is amazing and very reliable. I had an old one with outdated drivers and was unable to connect my headphones to my desktop. I saw the other generic bluetooth reviews and decided that if I want a good product, I need to spend the required money and I have no regrets. I had no problems with connecting my 5 year old bluetooth headphones. Just plug and play, no need for installing any drivers on Windows 10. Rest of the instructions are given in the booklet. Need to add your receiving device from settings and you're good to go. Reception is clear and has a good range. 5 stars for both the product and Amazon.
    Just purchased this device for my pc, instead of showing up as a bluetooth adapter, it showed up as a 'csr radio' and I was unable to use ps4 controller on bluetooth. Was about to return, but then, I realized that the real flaw was in the drivers and not the device itself. Whoever is buying this device, please don't install the drivers in the link, let windows 10 default drivers do their work, now works flawlessly.
    Windows8/8.1/10ではUSBに挿すだけで利用可能とありましたが、自分の環境では自動でBluetoothアダプタと認識されず、手動で下記手順にて解決しました。デバイスマネージャー↓ユニバーサル シリアルバス コントローラー↓"CSR BlueCore Bluetooth"を右クリック→ドライバーの更新↓”コンピューターを参照してドライバーソフトウェアを検索”↓”コンピューター上の利用可能なドライバーの一覧から選択します”↓"Generic Bluetooth Adapter"→選択して次へこれでタスクトレイにアイコンも表示され快適に使用できています。自分の環境だけかもしれませんが、もし同じような症状の方がいれば参考にと書かせていただきました。スピーカーやイヤホンで接続していますが製品自体はとても満足しています。
    Déjà je ne remercie pas Amazon.. une semaine complète entre la commande et la réception de l’article (alors que j’en avait besoin rapidement !), vous m’aviez habitué à mieux. Bref, une fois déballée et aussitôt branchée sur ma tour sous Windows 10 (x64) rien ne se passe… je décide alors d’essayer divers ports USB de (2.0 à 3.0), idem. La clé n’est pas reconnue.. donc contraire à ce qui est écrit à savoir « plug and play »..Je suis donc allé sur le site du constructeur afin de télécharger le pilote (une première depuis je sais pas combien d’année, probablement l’epoque Windows XP ?), et que vois-je ? 410Mo pour un simple pilote bluetooth ?? quelle vaste blague… bref ! je télécharge quand même, j’installe (comptez 4 bonnes minutes pour l’install malgré un SSD performant !) et au final le nom « CSR Harmony » du logiciel n’apparait absolument pas dans Windows. Un comble…Cependant quelque chose est apparue coté « Ce PC » avec un dispositif Bluetooth enfin présent !!Chouette… je passe à l’action, à savoir apparaitre enfin mon premier dispositif (une manette PS4 en bluetooth), celle-ci n’a pas été trouvée… je regarde dans les options et trouve fin qu’il fallait cliquer une option pour activer la découverte des périphériques ! je valide et retente.. le couplage prends enfin lieu mais ca reste bloqué durant des lustres et au final se résulte en échec de l’appairage systématiquement.J’ai testé sur un autre PC (portable sous Windows 7 cette fois), clé USB reconnue et même difficultés d’appairage ! j’en conclu donc que la clé USB est officiellement HS ! magnifique ! pour un produit tout neuf et dont j’avais besoin rapidement, je me retrouve à devoir renvoyer la clé et perdre à nouveau au minima une nouvelle semaine ! vive la technologie, vive TP-Link ! c’est bien la dernière fois que j’achèterais cette marque ca c’est clair et net (déjà qu’extrêmement déçu de leurs routeurs 4G aussi à l’époque… ça ne fait que confirmer que cette marque est littéralement à proscrire).
    Ho comprato questo prodotto per riuscire ad utilizzare le mie AirPods sul pc fisso.Il trasmettitore arriva in una scatola ben protetta. Una volta inserito in una porta USB del pc si potrà connettere il dispositivo USB di propria scelta senza ulteriori passaggi.La qualità audio non è ottima, ma più che accettabile per utilizzi lavorativi.Consigliatissimo
    Lo compré porque el PC de sobremesa del trabajo no tenía bluetooth, y quería utilizar mis auriculares en el trabajo. Era un poco reticente a que tuviese problemas o cortes de sonido con los auriculares, pero al final todo correcto.Pros: - Fácil de usar, sin drivers ni nada extra. - Sin cortes ni cosas raras con el audio.Contras: - Ninguno.
