This unit was purchased to elevate a BT dongle from behind a PC in order to get more range.  The light works well also, but I really wanted the goose-neck USB extension.

Better than my previous bluetooth dongle that broke shortly after purchase.  This one has withstood so far and works great.  Picks up bluetooth signals from a pretty large distance.  I have had it connect to my headphones from rooms away.  Also allows you to connect multiple devices through the bluetooth.  Great addition for someone without bluetooth capability currently.

Product works great performing flawlessly with my newer BT devices.  Note to buyers:  Your BT device must meet the specifications of the unit as it will not pair with older devices that do not meet the specifications.

My Kinivo Kinivo Btd-400 Bluetooth dongle is a dandy!  I am very pleased with the it and the expedient service provided.  It is great to have a reliable Bluetooth go-to company as Kinivo for my needs.

This dongle brings bluetooth capabilities to older computers that do not have bluetooth device capability. Works great with bluetooth mice and speakers/Headset at an inexpensive price. Can't be beat!

Works as advertised, didn't have much difficulty setting up except I actually HAD to use the CD.  Windows wouldn't just install and use it.  Not Kinivo's fault.

Bottom line is it does what it needs to do - add BT to your PC quickly and easily by popping this into a USB port, and has been working flawlessly since allowing me to connect all manner of BT devices (keyboard, mouse, head set, etc).

I've installed the wireless jack and have since forgotten I've had it.  I used it to connect my dish network reciever to avoid an additional $5 charge every month due to the contractual agreement.  They only want to make it convenient to order PPV events via phone line connected to reciever.

I was sceptical at first but when I installed the device and tested the operation I was impressed.  Part is kind of bulky but it does work!

I ordered this dongle as a package with the Kinivo headphones. I ordered it because my Toshiba laptop did not come with Bluetooth built in and my cheap, old Insten dongle would not work with W7 without fresh software. I opted to install from the SW CD and had a few BT components fail on installation. What I got was more than I needed. I can connect to my Samsung phone and the Kinivo headphones just fine.

I may have to play around with the settings to see if I can get a little more range. The signal breaks up some at 20' if I go around a corner at home. I don't know if I have the eco or high power mode engaged.

I purchased this wifi adapter along with my new Raspberry Pi.  The adapter was very easy to setup on the Pi, using readily available setup instructions to enable wifi on the Pi and have it recognize this dongle.

I was able to find this device for $18 and it was more than worth it.  I was surprised to see that no CD came with it, but it didn't need one.  Its a plug and play device so it just installs the drivers itself.  The wi-fi function works right after installation and boot up.  It was a little tricky finding the drivers to get the bluetooth to work, but after a little research I found it and everything is working.  This device fixed 3 issues with my computer.  This is basically a 3 in 1 card: 2.4GHz, 5.8GHz, and Bluetooth.  No more external Bluetooth dongle now lol.  This is a great buy and a very inexpensive yet beneficial upgrade to any laptop.

The sound quality and ease of setup are very good. This is a good product that will serve many buyers well. The problem I had is that the 12v outlet in my truck is unswitched, so the BT unit never disconnected from my smartphone when I parked. I couldn't hear phone calls or audio while I was in my house because the phone was still connected to the BT unit. I'm going to just use it for playing music and will just have to manually unplug it each time.

Isolated the feedback from the BT hands free device played through the car's radio accessory port. Works well.

Unfortunately, the README on the installation DVD is written in Japanese which makes installation/configuration somewhat cumbersome. Regardless, I was able to install the drivers (on windows 10) and the device was recognized. Double clicking on the "Bluetooth" device (in the "This PC" screen) allows me to pair the device to my cell phone (as a test case). I have a bluetooth project I am working on and that's what I really needed this device for. My project is not ready to connect, but it looks like this until will do what I need.

i bought this usb bluetooth dongle so i can transfer my files to my phone. but all it does is nothing.the icon shows up but that is all it does.

Every once in a while, my computer would just stop recognizing there was Bluetooth connected to it. I'd have to open up the Bluetooth settings screen before it would work again. I'm not sure if that was a problem with my computer, or with this dongle though,  but I thought it was worth mentioning.

Great product to extend your Wi-Fi network signal.

Perhaps a personal issue, so I'm not blaming the seller.

After I received the unit, I put it into my Toshiba L755-M1E9 (Middle Eastern variant, purchased it while overseas years ago). For a month or two, it worked fine. Then my PC just turned off, no Windows 10 crash screen (blue screen) or anything. When I turned the machine back on, the Bluetooth had disappeared. There was no Bluetooth radio in Device Manager, so I booted into Linux and saw if `lspci` and `lsusb` would show it, but it wasn't there either. This was a bit of an issue, because I bought this combo card to go with my new Logitech MX Anywhere 2, as it absolutely required BT 4.0 or I needed to use the USB dongle. However, I decided to ignore the issue, and go back to using the dongle, but a few hours later the PC halted again, and I just decided to remove it.

This laptop has no glaring incompatibilities at first glance, so I can't tell why it was halting violently. Since the dongle was cheap, I may purchase another one, or just finally get rid of this junker.
