I wanted to test the mixer, but today tx fees went up to 142 sat/vB, so for now I will test the the front end.
Front-end is clean and simple, but it contains a lot of details that many not want it. If thormixer.io shorten the home page to Anonymous Bitcoin Mixer / BTC Tumbler, Letters of Guarantee / PGP key, and FAQ - Bitcoin Mixer Frequently Asked Questions, and move the remaining parts of the home page to other pages then it will be better.
I checked the page for any traces, website capturing keystrokes, third-party cookies, and Blacklight Inspection, but I did not find anything, as the site is good in terms of privacy. Inspection results

The service fee is reasonable, but I did not like the idea that the mixing service is limited to a maximum of 6 hours. This will reduce the time of tracking services as they will track all addresses that have a balance similar to the deposit balance within 6 hours or 36 blocks (not a lot of data).
