Has anyone dealt with Expansys NZ?

Has anyone bought anything from Expansys NZ before? They're the only "local" retailer that has the tablet I'm after, but they're obviously foreign.

Secondly, the thing I'm looking at is a Huawei MediaPad M5. I need an Android test device for Unreal Engine that will get OS updates and last for a few years. I'm only going for this one because it's a recent release. Any other recommendations? The Galaxy Tab S3 is only running Android 7, which I found odd for a tablet that came out earlier this year.
