I found my post on bitcointalk...

"In that case allow me to report that I have used Anonymixer and Whir successfully. I preferred Whir due to lower costs (a straight 1% across the board and cleaner, easier to use format}. I of course sent smaller amounts through before I trusted them with larger amounts.

It is important to use mempool.space to know when miners fees are lower."

So send a few sats through whir.to or anonymixer.com to prove them and then go for it!
