This worked well on my MacBook Air once I had found the correct driver on the web, but this was not easy, because the one found through the Lindy site is wrong, out of date and doesn't work with OS 10.15! The trick is you have to work out that the ethernet bit inside it is not made by Lindy, it is called an Asix AX88179, and when you find the Asix website, you can eventually, on a poorly-organised site, find a driver that works! So basically the problem is bad information from Lindy.
