Sure do. I'v reviewed them over at crankylinuxuser.wordpress.com , my blog.

Tl;dr: They're worth it. Well worth it.

And you with the CH340 serial driver, you won't be FTDIcked around.

Well, in fact the CH340 can be a problem, at least for Macs.

The manufacturer's own driver is unsigned, so for years you had to disable kernel security features just to run it, and with the latest OS X release, it causes kernel panics outright.

There is an excellent third party driver at https://www.mac-usb-serial.com, but the $7 for that (in itself a very reasonable price) start pushing the clones back toward the price range of the originals.
