The only GDPR plug-in I found suitable for my purposes

It looks good, it is customizable, and has the right display options.
And most importantly – it actually works, and has great support in case you do run into a problem. Support is very attentive and quite quick to respond.

Also, updates are regular but not annoyingly so – and they improve functionality and solve whatever minor issues there may be.

I am really happy with this plugin and can definitely recommend it.
