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 bought this for the spray bottle and am really happy with it, for sure going to be using this for when I'm travelling.
Though the plastic is a bit flimsy (I mean, for the price it's not too bad) once filled with cream/liquid or anything you're using it for, the plastic isn't a big concern.
I would really recommend this, even for everyday use - I'm definitely going to be using the pump for moisturiser and plopping it in my purse. It comes with a plastic piece to stop unwanted liquid being pumped out which is great.
