Bests & Worsts Reviews from Amazon

I researched all brands and even after reading the 5 star (but still negative) Amazon reviews, I still bought this and I am glad I did. I called Water Pik and they confirmed I would kill the battery if left it on, so I now charge after every use and ONLY when I home home to watch the charger light go out. After a month I learned to use on high and just fill 4 times, once front, then back, top & bottom. Beats having a tank. Other than TERRIBLE battery design, biggest complaint is that it is not designed to fully drain out of the plug hole (raised higher inside than the water housing). Pulling the bottom off every time is ridiculous. I just shake it, then set on a paper towel because it leaks for awhile, and leave the plug open to air dry.
