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 me!<br /><br />Nice 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 doesn't come attached, and I wish it did since I'd 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'll see.<br /><br />The 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, too.<br /><br />Unlike 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.
