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.
Size is compact but coverage is good. I like the lighting options and the extra magnifying mirror which is handy. Regular plug option would be handy too but did see there seems to a USB outlet but haven’t looked into how that works.
Great quality, good packaging. Lights are enough to lighten up your face but not so much to disturb you while working. 15x magnifier size could be a little bit bigger but does the job. Loved that you have an option to either use cable or batteries. Highly recommended.
