The only Con of this mixer is the power out LED display isn't working.  Doesn't affect sound just no bounceing lights to the musi.  All the other LEDs work.

We did not compromise on the audio quality making it a worthy member of Stanton's Superior Sound Technology' series. The RM-22 features audio specifications and internal construction that rivals mobile and small club mixers costing three to four times as much.

Due to previous buyers not being honest about the items when they receive them this item is a AS-is, where is sale. No returns.  Now if you have a problem with it I can work with you on it. But this thing is working like new now except for the output light bar.  Sounds great.
