KINIVO BTD-400 Bluetooth 4.0 USB adapter - For Windows 10/8.1/8 / 7 / Windows XP/Vista

Long story short: buy this if you want a headache-free experience with a Xbox One Controller.Practically every bluetooth dongle listed on Amazon uses Qualcomm's CSR8510A chip - with drivers last updated in 2012. Now, the date wouldn't be much of an issue if the damned chip worked with an Xbox One Controller - the latest one that has bluetooth built-in. I tried two different cheap models, and both struggled to get connected to the controller, and would NEVER reconnect - necessitating a full disconnect and re-pairing. Painful.This dongle uses Broadcom's BCM20702 chip, and it works flawlessly with the Xbox One controller (with Windows' default drivers). I'm also using a Logitech K480 keyboard simultaneously and everything works A-OK. Connecting was fast, and everything reconnects in what feels like a second. This is ~4X as expensive, but that's totally worth it, because the alternative just doesn't work properly.

Make - The look of the product and the feel of the plastic on top is good... not cheap, compared to other Bluetooth dongles.Range - Its standard as they have mentioned in its features.(My Experience 6 meters for portable sound bar in straight line after that sound is crackly...for mobiles n headphones its good to go upto 10mtrs.)Price - Its worth the price this sites offer.(Rs.649 on amazon)Compatibility - If you are looking for dongle that runs good on windows 10 then this device does it. I had one dongle earlier running on windows 10 and connected portable sound bar to the system, after few mins. sound use to go blank all of a sudden, then I had to do few tricks to again listen to music, thought of changing the dongle and found this one, I ordered and plugged the device in USB 3.0 jack and since then all Bluetooth devices connect to the dongle in an instant, without any driver installation on windows 10 it connects just good... I would recommend It.

First off I'll go about the things that are good about it -It uses Broadcom bluetooth drivers, which is a good thing for future updates and wider compatibility,It's small form factor, however I didn't say it's tiny,Good performance, very low latency rate between devices while transmitting data.Now the bad part-It's built quality is cheap, like really cheap, as you could see from the other reviews. You won't believe the knock-off like plastic parts and the way they are being held together. It's like really poor use of glue and will come off without even any big force.So I bought this for my laptop as my inbuilt Qualcomm Bluetooth chipset stopped working with my audio devices, there was noticeable lag and sudden freezes, though file transfer was working fine without any fuss. I use a Sony SRS X3 and Jaybird Freedom for listening music and only for that purpose I needed an external adapter and I bought this. As I said I didn't have any trouble performance wise and I was happy with that. I found about the build quality in the hard way when I went travelling. The adapter was plugged into my laptop and stowed safely in my Everki Concept backpack(which can hold upto 17' laptops, mine is just 15'. So there's plenty of space for protection) and put in the overhead bin. After I reached back home after the trip I took out my laptop and found out that the top half of the plastic part is gone, just broken off from the bottom. I thought maybe this happened due to some turbulence or something. And again I went on to another trip and when I returned and opened up my backpack everything broke bit by bit. I could see all of its parts came off. It was fortunate that all of the parts were still inside the bag, so I picked them up and put them back together without damaging the chip. And I stick them together with Instant Glue that I got for 5 bucks. Voila, it works again even though the top half is still missing.I'd like to say that this was not the only dongle that was connected to the laptop the whole time, I had a Logitech receiver for the F710 Gamepad(3 Years) and another Belkin receiver for the M450 Wireless(2 Years) mouse both of them was plugged in along with the Kinivo Bluetooth adapter(5 Months). I've never taken out both of them during my trips. So, it's definitely the fail of the build quality.Verdict will be that if you're planning to buy this, once you get it do a overall cover before actually using it with some instant glue to protect it. Or at the least do it with some tape and you will be safe. Or good luck taking it of during traveling and searching for it later on.

This is a fantastic product, exactly what I wanted - to connect my Bluetootlless PC to my stereo system.It arrived before time, in pure amazon style.It was superbly and professionally packed, both by the manufacturer as well as by amazon.Unboxed, plugged and was picked up immediately by Windows 10, drivers installed and ready to go in minutes. Superb installation experience.It transmits great. Good streaming, no drops. The seperation in my case is just about 10 feet and haven't bothered to see how far it can go.Sound quality is great.Am real glad that I bought this sweet little device.I'm sure you will be too.Cheers!

Today i have got the chance to use it as it was delivered to me in the morning. And one word which comes in my mind after using it is fabulous. I am using windows 10 and the product works like a charm. I was in doubt earlier that whether it would support windows 10 completely or not but now i realise that i haven't done anything wrong in purchasing it. Believe me guys it detects immediately my soundpeats QY7 bluetooth earphone which i also purchased from amazon and i have connected few phones also and it is working fully with each and every bluetooth enabled device. The sound is transmitting fluently from my computer to the earphone and the clarity is as perfect as if i am using a wired headphone. So those who are willing to purchase a bluetooth adapter i would say that it is the best in the market. Go blindly and purchase it. You won't regret. The packaging was also good. Prompt delivery by the seller. Thanks.
