Woohooo! I was so excited to be chosen to test the new Sterline water flosser! I've seriously ALWAYS wanted one of these. I hate flossing and always heard good things about water flossers. Well, the Sterline is about as awesome as they come - this baby has 10 water pressure settings (start at the lowest one, is all I can tell you), 1,400 pulses per minute, and comes with six different nozzles including an orthodontic tip for braces, a tip for periodontal pockets, and a tongue scraper. The cord rolls up neatly inside the unit, and the tips store inside the lid!
After I got over the learning curve of keeping my mouth closed while flossing so as I wouldn't gush water all over the place, using WARM water, and NOT to use the highest pressure setting for my sensitive gums, I'm loving this thing! It seems well made, sturdy, doesn't take up a ton of space, and comes at a great price.
Only con: The unit is a little loud (fine at low pressure, a little more annoying at higher pressure), but it's tolerable for me (and the neighbors too, hopefully).
