does what i need there is no real instructions with the product [SEP] i have never used a water flosser before but my dentist recommended i do there are not much instructions with the product what there is is not in very good english i get water everywhere while using this but i am also new to water flossing i think i will save up for a traditional corded water flosser i think a smaller devise in my hand would make it easier to use i am not unsatisfied and i will keep this and use it even after i one day get a corded flosser this one will be good to have for traveling
