I just got this gizmo. My 2 paise worth. It's not a general purpose cleaner but IMHO extremely useful for a first time clean of brand new sealed and garage sale records . IME all new LPs have a fine layer of micro dust clearly visible with a LED or CFL light. I tend to use a Mo Fi felt pad to gather the dust in one place with a clockwise and anti clockwise motion and then use the gizmo to remove the dust. DO NOT use it on records if they are OTW dust free. Ditto for a first time clean of garage sale LPs.
At current exchange rates my 2 paise is way less than 0.2 cents !!
