For someone who doesn't mind the intense blue flashing light, it's great. Cheap, easy to install, and functions without interruptions

I bought it for a connection to my Logitech speakers, which already have Bluetooth capability, and this specific Bluetooth, which I connected to Windows 7, is not worth even 1€, let alone less than 5€, as it cannot play sound. It connected to the speakers for 3-4 seconds!! Sound never played! Luckily, this time I didn't throw away the packaging and returned it. I immediately ordered another, more reputable brand

I ordered it for use on a Linux operating system. It worked right away and hasn't had any issues (e.g. disconnecting) for a month now. It's also quite cheap, so I recommend it!

Personally, I ordered it to have the ability to use the controller on my computer. It arrived the next day and works perfectly. I wasn't sure if it would work for its price, it seemed a bit cheap, but so far I haven't had any problems!
