I will say proceed with caution with bitmixer.io
I also had one good experience with them.
So, I used them again a month later, the following Saturday.
After not receiving my coins I tried contacting them through their website that kept giving me an error to say try and submit my message again.
After repeated trying with no success, I contacted them here.
Instead of taking the facts and looking into the issue, I was met with accusations the coins were sent, then I must of spent them.
After having to trace the coins my see I see they are residing at 1LWiU1uaQkdrf4x1ziDuW7RvJKRhE2RStY
After repeatedly asking if that address is connected to them, I finally get a No, after being further accusations of transferring my coins to that address.
First, if their level of "professionalism" is abysmal.
A non functioning contact on their webpage then accusations with no investigation.
2nd, if I transferred my funds to another address why in God's name would I give them the address asking if it's theirs?!
Proceed with caution with bitmixer.io
I don't believe they are not connected to the address my funds are still sitting at - 1LWiU1uaQkdrf4x1ziDuW7RvJKRhE2RStY
At this point I don't believe they are complete thieves.
I believe they are incompetent and too lazy to thoroughly investigate.
I plan on following 1LWiU1uaQkdrf4x1ziDuW7RvJKRhE2RStY until I receive answers as bitmixer.io has no interest in customer service once they have acquired your coins.
User beware.
