Sounds good, I just bought a Y5P from Powerbuy, it's great and I'm happy with it. I was looking at Lazada too, but I had a really bad experience of buying a USB flash drive from a lazada vendor that was fake. I went through the returns process and Lazada basically didn't care and only replied with 'return to sender' after the time period had elapsed so all I could do was leave the seller bad feedback. Because of that I wouldn't go with a cheap phone, but I'm sure they're fine.
The thing I found out from the PowerBuy seller is that all the latest Huawei phone don't have Google services - so no Youtube app, no Play store and no location on LINE (so you can use location-related services). I don't really care about that stuff - the Huawei app store seems fine and I can watch Youtube through the browser.
