Just thought I'd add to the previous posts here to say that Car Mechanics mag, in the October 2020 issue, did a 7 page review of many of the fault code readers on sale today. If you can get hold of a copy (they sell back issues) it makes for very interesting reading. Their best buy recommendation, balancing functionality against price, was the Foxwell NT301 @ £69 - I've seen it much better priced. for example:

If you want a detailed description of functionality go to Gendan's site:

They - Car Mechanics - also highly recommended the Autel Autolink EOBD Scan Tool AL419 although it was a bit more expensive.
However if you can get a look at the article it goes into considerable detail, including some practical testing on actual vehicles, which they used to asses the different devices, I would strongly recommend it. It's not often you see an independent product test with so many different makes. - They tested 13 different devices with the accent mostly on the more affordable models.
