Review (5/5): Great water glosser!
I could not remove water tank. It would not twist off as instructed. I tried warm water for 2 minutes. I know, as some smarty said, that water can be added to the hole at bottom edge. But I would think the tank should come off to clean with soap and water. I even contacted customer help. But they gave same “hints” to open. My advice Do Not Buy This One!! Originally a 1 star!
UPDate.. I give this 5 stars. After several contacts with customer service. I got a replacement. The water tank is easy to remove for cleaning. The device is easy to clean, use, and being it’s portable I can carry it in my suit case when traveling. I recommend this water flosser for quality and price.
