easy use comfortable could have longer nozzle [SEP] i use a larger plug in water flosser unit in my full bathroom on upper level of house which has a large capacity water reservoir i typically take my time and use it at night before bed however i wanted a unit on my main floor bathroom for quick use during the day without having to go back upstairs or for use if i am going to be gone all day and want to take it with me therefor i have been keen on getting a portable chargeable flosser that and my first floor bathroom is super tiny with nowhere to put a typical flossing unit nor anywhere to plug it in this is perfect for menice unit right out of the box it is attractive feels comfortable in the hand as is easy to get it going while it comes with instructions it is easy to figure out very intuitive usb cord is good length the port that plugs into the unit has a pop in cover anti fouling rubber stopper it does not come attached and i wish it did since i would rather not have that area exposed to water i sense that i will lose that cap soon enough or just forget to use it we will seethe unit comes with four attachments all for doing different jobs so unless someone has a need for this unit and for an attachment for something different than what you need i would say this is for solo use good sized water reservoir toounlike my main unit this one has a fairly straight nozzle in comparison this makes it a challenge to get behind the rear most molars if the nozzles were a little longer with slightly more curve than it has i would consider this a perfect product
