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.
An Australian "smart" powerpoint that isn't a plug-in accessory such as this is pretty unique. It really is a very nice looking product when installed and pretty straightforward to wire, just like a regular GPO. It works as advertised and I had no problems connecting it to my wifi network. The Tuya app which is used to control it is OK as well. There was some stray foreign text in the device name in the app (I think it was probably Chinese) , but this was easy enough to edit. I also didn't have any problems getting the Tuya Alexa Skill going. I would have given it 5 stars if the touch power buttons on the front bezel weren't so close to the plug.
