this mixer was bought for a present for me and i was very impressed with it, i use this constantly, although its a 3 channel mixer it essentially gives you 5x inputs and a Mic feed, i currently have 2x turntables and a digital controller, plus a aux out from my PC and a mic input and can swap between inputs at the flick of a switch. the BPM counter is "OK" and does help to give you an idea of the BPM of the tracks playing which comes in most andy while playing vinyl, if like me you are a complete beginner, but its not the most precise so do not solely rely on it but its there to give you an idea of the current BPM. ther mixer itself is solid with a metal face plate that is easily mountable in a case or rack and has holes for screwing into such mounting. it also has clear markings for each knob and button function whereas some mixers i find are not all that clear, but no problem with this at all. worth the money for sure.
