The first three units were all from waterpic but all broke in about one year due to the same water leakage issue between tubing and base

The unit worked very well based on my wife’s comments as a very experienced water flosser user

I believe matwave can provide a 2year warranty means the product should last longer or much longer than two years

Among them matwave v20 looked different at least the touchcontrol design is in line with up to date electronics operation method
