Interesting mathematics... 93% 1* and 7% 2* yet the average is 1.9*. Come on, this is donkey level stupid mathematics, anyone with very basic maths can see the average isn't 1.9.

Anyone with very basic physics can see the waterblitz can't do what it says. You can't make pressure out of nothing. This is just a hose nozzle at an inflated price, you can buy something just as effective from any garden centre or DIY shed for far less.
