Using this flosser was very intuitive. It is easy to fill and simple to use. There are 2 tips so it can be used by two different people. One word of caution – don’t turn it on until it is in your mouth or it will squirt water all over the bathroom. Also warm water feels nicer on the gums than cold water does.It is cordless and the battery seems to last a long time on one charge. It is also very easy to refill which is a good thing because to do a through job you need to fill this up twice. There are 3 different settings: normal, soft for sensitive gums and pulse to massage your gums.
