No Warranty
Only buy here if you want a phone without any warranty. I've ordered OnePlus 13 with OxygenOS, when I received it, the display wasn't working at all, the touch wouldn't work or anything else. I've contacted support for warranty, and they blamed the fault on me for wanting OxygenOS flashed on the phone. When I went to a repair shop, the display was completely dead upon arrival, and not a software bug. The repair price was half of the phone price!!! 300$. I don't recommend buying from giztop, unless you understand you won't have ANY warranty whatsoever.
