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.
This is definitely a good portable laptop, though a little under-performing processor (when rendering video edits), and the sound jack has spoilt within days. Luckily there is USB and USB-C connectors, thus still possible to connect headphones using the USB connectors. Definitely not as hardy as some of the older models, but wifi connection is strong (especially 5G) and good for students' use.
