This Review Title is Affordable & Effective, But Has Pooped Out and the content is: I had major dental work (extractions, jawbone surgery, grafting, dry socket, infection, implants) and needed something to help keep the area clean and emptied-out, given that my tissue didn't bond properly to the implants, thus allowing food in.<br /><br />The unit has generally worked well for me and I like a lot about it, including how long it would go between charges.<br /><br />Things I don't like:<br /><br />1.  It seems impossible not to taint the cleanliness of the water reservoir when opening its little door.  I suggest filling the reservoir with hypochlorous acid (nature's germ killer) and letting the hypochlorous disinfect the door.<br />2.  It is too easy to accidentally turn the unit off when using it, based on the location of the on/off button.<br />3.  I wish the unit would default to the last-used power setting, but I have had to reset it each time.<br />4.  My unit's battery appears to be failing.  The unit will charge appropriately, but then only run for seconds.  If I turn it back on, it will run another few seconds, then the process repeats.  As far as I know, the unit can't be opened to replace the batteries, but correct me if I'm wrong..There are other information for this review, one is This reviewer did purchase it and the other is 0 people think this review is helpful.
