Dodgy, dodgy dodgy!!!!
I purchased a Samsung Galaxy S7 Edge it worked for a couple of months the screen blew and it took three months to repair after going to Auckland and Melbourne (the screen was replaced. After it came back two weeks later it couldn't be charged. It went away for two more months. Another phone came in an unsealed box which only lasted a couple of weeks and couldn't be charged again. They say they open the boxes for quality control which does not make sense. If you buy a new phone it comes in a sealed box, their ones don't. Never buy a phone online, go to a shop. Becextech customer service is appalling. I am just so angry about it all I have given up on getting a phone from them that works reliably. I think it's just better to move on and warn other people about them, The case managers are in Indonesia and do nothing for you. they totally ripped me off.
Go to a shop to buy expensive items.

Approximate cost: $1527
