Aside from that, it does what it says on the tin (well, sort of). I don't use Bluetooth headphones with my PC any longer, so I can't comment on sound quality, but other devices (keyboards, cell phones, etc.) pair easily enough, don't drop connections, and appear to have the expected 30m range. Additionally, I've enjoyed Kinivo products I've used in the past and thought their build quality to be fair enough for the pricing.
This is the third desktop PC Bluetooth adapter I've owned. Over time, I've had to swap them out as the Bluetooth standard changes and devices improve. The first set of Bluetooth headphones I ever owned (despite being a rather uh, well-known brand) had horrendous audio quality and constant dropouts in the days of the older tech. I've been satisfied with the performance of the newer Bluetooth audio devices and the chips in my newer phones; I think we've really reached the point where 'cord cutting' headphones and data transfer between mobile/IoT/etc. is no longer an exercise in frustration (mostly).
Onto my issue: I purchased this dongle because it was Bluetooth 4.0 and says everywhere that it supports Low Energy or BLE. I use Windows Insider builds, and the 'Your Phone' app has been rolling out screen mirroring for Android devices. My phone is not compatible yet, but since it's a Pixel I imagined it was only a matter of time. The second requirement is a BLE capable adapter.
Well...the way Windows defines that and the marketing terms start to get a bit confusing there. As you can see from my screenshot, this does not support the BLE role, and is therefore not compatible. I imagine perhaps a BLE 4.1 or 4.2 device is required--unfortunately information is a bit slim as it seems most Windows Insiders able to use the feature are doing just fine with their Surface devices.
Also, if you visit the Broadcom website it assures you that there are no drivers required for Windows 10, it is indeed plug and play and you have Bluetooth. However, the drivers installed by default were version .750 from 2015. Windows Update didn't really do much about this, as much as it loves overwriting drivers for my other devices. The Windows Driver Catalog has version .1010 which are a full year newer and seem to offer a bit better performance, but I don't have any real metric of that. Updating drivers in this way (via extracting a .cab, installing a .inf, and manually loading them through Device Manager) isn't a major headache but probably not super intuitive for the average user.
TL;DR: Bluetooth Low Energy doesn't mean the same thing on a 4.0 device vs. 4.1 or 4.2. It appears some newer devices will begin to require 4.2 for full functionality, yet there doesn't seem to be much of a selection available at the moment. I wouldn't discourage you from buying this dongle if you need Bluetooth and it's not really a big expense anyway. It's just likely that you'll need something different before too long.
Should Have Researched This More First

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.
