Review (1/5): Not as Powerful as the Water Flosser it Replaced
I bought this unit as a replacement for my Ailifefort flosser which I dropped and broke the plastic on the water reservoir. I found that unit superior to this one, but alas it is no longer available on Amazon. The main issues are it was simply more powerful which allowed it to do a better job and the reservoir was larger. I fine with the new unit a single tank is not enough water to floss my entire mouth.
Since I know I can find a water flosser that better meets my needs, I'll keep looking. I wouldn't buy this unit again.
REVISED 6/16/2020: Reduced rating to 1 star. This unit is worthless. it has absolutely no pressure even after letting it charge overnight on 2 different nights just in case it the batteries were low. Very disappointed with this purchase.
