Hi I'm from Peru,
I use Z3X BOX few months ago, this box is quick and easy to understand for interface graphics and descriptions of cable types,
to classify cell phones in alphabetical order or by the model to unlock, has variety of modules and upgrades of new phones from Samsung and LG.
Has Calculators Blackberry, Alcatel unlock by IMEI with very efficient results.
Is the only solution for unlock, flash, repair IMEI, software updates constant.
There is no other that compares to BOX Z3X for the reasons outlined above.
