Title: Interplak Dental water jet WJ6RW
Review: This is the second WJ6RW unit that I have purchased. The first one lasted around 4 years before the handle split. This unit had great power and was used on the middle settings or slightly lower.The second unit, just purchased, does not have 1/4 the power. We have to operate it at the highest setting which is less power than the lowest setting of our original unit. They are the same model number and look identical. The power is usless even at the highest setting.
