I have a very good experience with Gearbest and I want to share it.
At 25th of March I ordered for my wife a Xiaomi Redmi 3 and black Nillkin Frosted Shield case for it. Order was shipped out in 24 hours and i got a tracking number for it. It came to Ukraine at 19th of April and both of us are extremely satisfied with those products: they are genuine, have a great build quality and a price.
So I must say it was extremely good, cheap and fast order. I'll definitely came back to Gearbest and make a new one (and I already ordered 64Gb Mixza Micro SD card from them).
