Review title is Comparable to the basic Waterpik portable with a few improvements and extras [SEP] This unit is comparable to my very basic travel Waterpik flosser. In fact it has several features that the basic model lacks for around the same price. This unit has three speeds, whereas the entry level Waterpik only has one. The fastest speed is comparable with the one speed on my Waterpik, and it’s the only speed I need. This unit has a charge light (blinks until charged) while there is no such light on the comparably priced Waterpik. This device has about the same sized reservoir as the Waterpik, but because of the design, it’s on the bottom as opposed to along the sides of the unit, the result being that it makes it a lot bulkier, which is unfortunate in a travel water flosser. Unfortunately, there is no advantage to this design as like the Waterpik, it begins to stop pumping water as the tank gets lower, forcing the user to keep the unit vertical in order to get to the water at the very bottom of the reservoir, which can become quite awkward while trying to get around the teeth and gums. I’ve owned several of these, and to be fair, they all suffer from this same problem.<br /><br />One more thing: this unit comes with a nice case and a stash of attachments (which are usually found in home units and don’t generally come with portable units ,) none of which I have much use for, but I guess it’s good to know they’re there. It does include two of the standard water flosser adaptors, so two people can use it.<br /><br />The only thing that remains to be seen is how long this puppy will last. This is my 3rd travel water flosser. I’ll report back should something ontoward occur, or if it continues to work well.
