After the failure of my old irrigator (hose ripped) I decided due to the fairly good reviews for this model. I do not use it as a travel oral irrigator but stationary in the bathroom. The design is an attachment not conducive, but (to drill holes in the ground and with hose clamp lock (not necessarily enjoyment!)) For some tinkering, there was also a solution for. Otherwise, there is nothing exciting to report: water pressure high enough and easy to dose, easy Bedienungbarkeit. However, the tube could be a little longer for my stationary use, but the WP-300E is indeed explicitly advertised only as a travel device. Tip: The initially but something stiff valve between body and water cups lightly with Vaseline.
