Bought this combo from Costco this week & reckon it's a solid deal;
Here is some features:
Removes up to 99.9% of plaque from treated areas and is up to 50% more effective than string floss for improving gum health. ^Our most popular Water Flosser^Includes: 1 ultra water flosser, 1 Nano water flosser,1 deluxe soft sided travel case, 1 tip storage case,12 accessory tips
Are these actually effective? Dad got one two weeks ago and I didn't take it seriously.
