Extremely satisfied with this calculus remover.
I'm a coffee drinker and smoke cigar. After a couple of weeks of coffee and cigars,, my teeth get stained with tar accumulation.  My Meeteasy got rid of the tar and stains on the very first use. I didn't have to apply much pressure so my teeth and gums did not hurt. Does not replace a professional cleaning but it's great to use between dental visits.
