I have bought a device from them (Z18 which comes with their own Android flavor and the ratio launcher) and my personal experience wasn't very good: updaters that don't work, their community support board that is not very active, I had to download and flash a ROM from a dubious website using some obscure Mediatek tool just to get a recent version up and running. It was a bad purchase and it doesn't inspire much confidence about their other products. I have spent several days over the last year or so to try and get an alternative open source Android distribution on it but no success yet. I wish I could install LineageOS on it so I can at least have a functional device.
