First of all, the product is covered by a 2-year warranty. It does its job well. It is quite beautiful. Because I was satisfied with its overall quality and reasonable price, I bought a second identical adapter for a cheap, simple, backup desktop computer that I have set up for a few years now.

I have transferred over 10 heavy image files in .jpg format and it only got stuck once during the transfer. Something that I don't think was due to the adapter itself, but something happened with Windows 10, most likely.

The main use I make of it is transferring image files (.jpg and .png), videos (.mp4 mainly), and audio (.mp3) to and from an MLS tablet that I have owned for about 2 years.

Its range reaches up to about 100 meters. It is compatible with USB 1.1/2.0/3.0 standards. The package includes the adapter and a CD with drivers and the instruction manual, which is not translated into Greek. However, its box is translated into Greek.

You should generally know that file transfer speed with Bluetooth lags far behind compared to a USB cable. But it is less cumbersome and much more comfortable and easy.

The company LogiLink is German, but this particular product is manufactured in China.

In conclusion, I recommend the LogiLink USB Bluetooth adapter V4.0 Dongle BT0037, although, of course, there are many other worthy adapters on the market. Like those from ASUS, which is an amazing Asian company.

Positives

• It is reliable
• It has a 2-year warranty
• It has a long range

• Comes with a CD with drivers and a user manual

Negatives

• The instruction document is not translated into Greek

Owner for 1 month now and I can say that I am completely satisfied with the product.
I have been looking for a way to add Bluetooth to my desktop for a while now, in order to use headphones without any delay. I found this one that supports apt-x low latency, so there is no delay in sound when watching videos, which is the main use of the headphones. Here I should note the most important thing, that I am using the Sony h.ear On 2 headphones, which also support apt-x low latency. With simple Huawei Bluetooth headphones that I have, there was a slight delay in the sound, you would first see the speaker's mouth move and then the sound would come with a delay of about 5 ms. This is not the dongle's fault. You need to get headphones with apt-x low latency.
I made the mistake of inserting the disc to install the drivers and for hours I couldn't get them to work more than once. Then I removed the dongle, uninstalled the drivers, and simply connected the dongle and let Windows 10 do its magic. It worked immediately as soon as it downloaded the drivers and I have no lag at all when watching videos on YouTube and movies in general. Also, every time I turn on the headphones, they automatically connect without any delay (within 1 second).
At first, while the sound was working fine, it would occasionally have some rare interruptions. Also, if I moved more than two meters away, it would lose signal. But now it doesn't do that anymore, it's like it fixed itself. Maybe it was a driver issue, but now it doesn't have any interruptions or disconnects within a range of 5 meters. I highly recommend it for those who have apt-x low latency headphones or speakers.
