Pretty good, does what it says.

The only gripe I'm having is that after a few days it doesn't really let me open twitter with the button "view on twitter"

Works fantastic, exactly what you expect. There was a little bug but the developer was quick to fix it. Cheers!

Simple but effective X redirector, which is all I want. Someone sends me an X-Twitter link, I click it, and I get it in X Cancelled (from Nitter).
