Help choosing a bluetooth dongle for win 10?

Hi,

Could anyone recommend a decent bt 4.0 usb dongle that works perfectly with win 10? I bought one of these mini csr8510 ones cheap, and it's an absolute pile of junk. If I leave it plugged in It regularly stops other usb devices from starting upon boot, and even when it does work its very flakey, refusing to discover, or pair half the time.
Checked event viewer and it's kicking up event id's 2, 6, 18, 28, and maybe one or two others. A couple of those id's iirc are non low-energy compliance, and inability to store bt link keys.
I've looked on ebay/amazon, and the majority of the available ones all look similar, and probably identical internally, but check out the reviews and sure enough, multiple users having issues, usually with win 10.
I just want one that will have no issues, even if it costs double.

Tried all the usual - different ports, alternative bt stack, etc., to no avail.

Edit: Working now, just about, but now when I boot up with the bt dongle inserted, my wireless keyboard doesn't work, until I unplug its (usb rf) dongle and plug it back in. Most annoying.

Has anyone found a particular make/model that has given them no problems? Or are they all the same, based on this csr8510 chip?

I have 2 of these in Win10 Notebooks, about as compact as they get and are version 4:

First Things First

The issue with drivers is an issue for the hardware manufacturers, it is not for Microsoft to change Windows to work with third party hardware drivers, it is the hardware manufacturers to make their hardware work, the other alternative would result in the need for a specific version of windows for every device built that is not identical to another. This is one reason why generic windows inclusive drivers appear "crippled" or otherwise less function rich than the Driver supplied by the manufacturer. The manufacturer will purposely supply Microsoft with a basic driver for a range of Hardware to keep certification costs down, (think of Graphics cards as a prime example)

Ok why do devices not work due to "bad" drivers

The built in drivers in Windows are supplied by the hardware manufacturers, not Microsoft, and are required to pass certain tests for the "works with Windows ..." or "Windows ... compatible" logos, to be applied to the hardware. Now Microsoft does charge for this certification (and I doubt it is that cheap ), what this results in is that a manufacturer will sometimes rely on the "Chip" Manufacturers to make and certify generic drivers which will work for their devices.

Also where the actual specifications are changes - as happens quite often in things where bluetooth is involved lately, the fact that the hardware is back compatible can lead for the manufacturers ceasing to support the older models EG, T4.0 when there are newer versions available (BT5.0) quite soon after the upgrade (the fact that this would possibly lead to lots of people buying the latest model is a factor in this of course - companies need to make money)

Later in the "Life" of the product, minor changes may occur, in either Windows or the components used in the hardware, that mean that the hardware no longer works correctly . This applies to both the Generic Driver based hardware and also to hardware where a manufacturer obtains and manage their own certification

The required procedure when this happens is automatic, but relies on the hardware having a different part number from the original and needing re-certification, which costs more money so does sometimes not happen.

With the cost of some items being held low due to competition as in USB dongles, the shortcuts in Certification described above are more likely to occur so there are two options left to us ...
We can either pay $25 - $30 to someone like Asus, or Belkin etc where there is more likelihood of the drivers being updated correctly, or we go for the $5 unit but expect to regularly buy another one as the driver fails
