Personal experience, thus, anecdotal.
Had to cancel a lazada order of a significantly cheaper p10 (1800) and bought from dierectd instead (2500).
I was aware of the price being too good to be true.
As expected, they only ship the order with just the phone. Non of box sets (charger etc). I'm okay with that as i could still buy a third party charger (well, still huawei's, still having supercharge) and still being ahead in price.
The delivery was good too. Listed within 3 days.
More importantly, it was advertised with 1 year manufacturer warranty.
Problem started the next day when the tracker shows the expected delivery was changed till next week instead of within 3 days.
The deal breaker was when suddenly later on the day, the warranty changed to no warranty.
Thank God lazada being reasonable and actually sided with me and helped cancelled the purchase even without screenshots (the changes was unexpected and the item listing was deleted).

If you found a good deal there, go for it. But be wary, and adjust your expectation.
As a rule of thumb, it's better if you could cod.
