Title: Interplak waterpik
Review: This a very flimsy unit with a a very hard switch to turn on. You have to hold the unit with one hand while attemting to turn on the switch. Not very friendly. The water storage resevoir does not come off the unit so that you can fill it under the sink, requiring aanother cup or glass to transport the water from the sink to the resovoir.
