Here is my review of the UniJoin site.
Website/ImpressionsAt first glance, the UniJoin site creates a pleasant impression because its use is intuitive, and all the necessary information can be found in the menu tabs. It is worth noting that the site is translated into 9 languages, which means that users from almost all over the world can easily find and understand the necessary information about this mixer. For example, users can familiarize themselves with the service fees in the Pricing tab, and answers to almost all the questions that users may have while using the site can be found in the FAQ tab.
The only thing I found odd is that the FAQ tab states that the minimum amount for mixing is 0.000 BTC, although this value actually should be at least 0.001 BTC. It looks like a typo.
In addition, I would note the Contact tab, namely the feature that allows you to generate a random name for the request. It seemed like a small thing, but such things show that the Unijoin team really cares about the anonymity of its users.
Well, I'd like to say a few more words about the design of the UniJoin site. It is made in pleasant colors and looks modern. In addition, the site is responsive. I checked it from devices with different resolutions (desktop, phone), and the site design looked good, i.e. without any defects.
MixWell, now let's start mixing BTC and testing the main functionality of the UniJoin site.
I was mixing BTC through Clearnet, although it's worth noting that the UniJoin site has a TOR mirror.- At the first step, we should specify in the appropriate fields from 1 to 8 addresses to which payments will be made after mixing. It is possible to select the percentage of amount distribution for each address and set the delay for transfer from 2 to 72 hours.
In addition, we can enter Unicode at this step (optional).

Click continue, and the site will ask you to pass the captcha. - Now we should carefully read the terms and confirm them by ticking the appropriate checkboxes.

- At this step, we should download the letter of guarantee and send the BTC that we want to mix to the specified address. In my case, the service fee was 2.0534%
Keep in mind that BTC must be transferred within 24 hours to the specified address, otherwise, the order will be deleted.

- Mixing in the process...

- That's it. The mixing is complete, and untraceable BTC(sats) have been transferred to the specified address after the specified time (3h 38 min)

Summary:Overall, I enjoyed using the UniJoin site. The site has a nice design, and all the necessary information is well structured, while the mixing process is intuitive and works smoothly.
