After I've bought a tv box from them and spent a week installing everything, I restarted the box and the date and time changed to somewhere in 2004. Tried to get relevant help from the after sale support but got irrelevant and non professional answers and needed to wait a day for each answer, while the box working worse each day (restarting itself, closing kodi several times a day, status bar disappearing etc.). Re-installed ROM just to realize it's exactly the same as the one installed, with the same problems. Asked to return the item for a refund and got an answer that you can only return it after a week... bad service and malfunctioned product.
UPDATE (5/2016) - I've sent the item back to the seller for a replacement and got another defective item.... they would only refund me if I'll send the item back to them. I should mention that it took them 2 weeks to take the item I returned from the post office and another week to send a new (and defective) item to me. Paypal didn't help solving the problem with them.
To conclude - they just don't care what customers think about them and don't know how to give a proper customer service.
