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.
I thought I'd give these a try as they are very cheap. However the pod doesn't seem to seal properly inside my Nespresso machine and sometimes just water comes out, then eventually the coffee. Other times it really struggles to get the coffee out like the granules are blocking the machine.
The ones that have worked have tasted great though, and I like the Lavazza coffee flavour, but it's a bit hit and miss whether the pod works properly or not.
