yea the price is usually noticeable, just buy your box from a reputable company that sell authentic boxes and you'll be fine. on the other forums i use theres plenty of people telling there stories of how there box lasted a few days or weeks and just blew up, theres a guy there whose box lasted a few hours. i bought 2 clones before thinking it was great i was making a saving, i got the boxes and opened them up to install hard drives, i was gobsmacked at what i saw, the circuit boxes were both burnt to a crisp, all the little transformers and little bits and bobs were rusted to hell, those boxes wouldnt have a lasted any length of time, needless to say i sent them back immediately, tho the kind of people that sell these boxes arent the greatest of people, i only got refunded for 1 box and told to do one. i started legal proceedings but didnt have a leg to stand on because of the payment system that was used... but thats a whole new story.
