Amazon calculates a product’s star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.
Roku Streaming Stick+ is sold on the Amazon Australia website therefor the clear implication is that it functions here and is compatible with local systems. It is not. Many channels (Roku and Amazon Prime in particular) are geolocked and the unit's power is for US outlets. It is sold through a reseller with again no indication it is not Australia compatible. Waste of time and money on the consumer's part.
Not getting involved in all the various VPN and IP spoofing stuff then this is rather useless in Australia with nothing much beyond Netflix and Youtube. Yes, you can fake a location and register in the US but then the stick knows it is not there and won't let you use app after app. If you want Amazon Prime and Netflix a simple Fire Stick is much better value.
The device works well for apps that don't have geofencing. The Roku website doesn't tell you which market you are in (I was using a web proxy based in the US) but fails to install many of the apps. There's no way to see what country you belong to and which apps are geofenced.
