was OK for a couple of months...then
Bought this item mid OCt. 2019 and thought it fine originally.  The biggest drawback for me is how close the power button and the degree of power buttons are to each other yet it appears that all power flossers look the same regardless of manufacturer. Now here it is mid Jan, 2020 and the power button is stuck on the highest setting. I use the flosser every day and did not expect it to go south on me after 3 months.
