Anyone here know anything about turntables and scratching/mixing?

The Isolator is decent enough too, really need to whack it up to get the full, smooth sounds goin but my speakers ain't loud enough and my neighbours lose it when I have it too loud anyway. Taken it out to a few clubs before, kicks in a treat on a decent system

The isolator is decent enough in the flat but agree, on a decent loud system it fails. Was looking at an E&S at the time but didn't wanna splash the cash when I was only gonna be using it indoors

make up your mind. Is it good or not?
