i was at oporto tattoo expo this last weekend and a lot of artist were using the equalizer proton from kwatron especial de black and grey artist
they sad that is a really good machine well built good motor and hits softer than the Cheyenne pen.
a thinking in buy one for trying. the price is good too is almost half of what a pay for my Cheyenne pen
are there some one using the equalizer proton ?
