I like the stuff Yongnuo makes very much! The reviews I've read and watched about the YN-560 are very good and it has some very useful features like a beep when its ready to fire again. They are also easier to use than Canons in my opinion. On my 430EX II you have to push the Set-button long to change the flash output, with the Yongnuos you have a four-way-dial for full-stop or 1/3rd-stop increments.
Today i had my YN-622c eTTL trigger in the mail and they feel very durable and well built, they also look very nice with the shiny surface on top. The feature set is impressive for 80€ triggers. Now I can change my flash output from the camera and won't need to go to the flash and fiddle with the buttons, which (let's be honest) looks not very professional on a portrait shoot.
I will buy a YN-565 with another set of triggers in the future when one light isn't enough anymore.
