Products received on time, certainly in better condition than advertised. The packaging for the delivery seems a bit flimsy though.

(Oppo reno4z 5g) delivery on time even 1d less but (y a tjrs un mais 😂) the phone was supposed to be in perfect condition (for me perfect condition is almost new especially at the price I pay them) but the tel has a problem display screen at home black no flat nothing surely the screen was changed and there were photos of the former owner it was not even reset (2jrs before understanding and being able to use, I do them and since it works perfectly) but I consider that when you buy it on a reconditioning site so known everything has been checked
