I like z3x box because it is stable and i have had no problems with it at all with it's user friendly interface this makes it my first choice for Samsung and soon going to purchase the LG Activation for it on the 12th when back in stock.
The easiest flashing tool also makes this box stand out from others with the 1-3 click functions and direct unlock for most supported models meaning we have little work to do when unlocking a phone
I buy and sell phones for a Living and would be stuck without z3x as i unlock phones which also adds value to the final sale price
good luck z3x team
