You will not regret it
This product is amazing. It’s truly an identical match to the original water reservoir that originally came with the waterpik. It’s true to size. Don’t hesitate to buy it you’re trying to save money. I’ve had my waterpic  for years and wasn’t quite ready to part ways with it because the water reservoir was dirty. This product have helped me keep my waterpik longer. I would advised that you dnt leave water in I recommend drying it or allowing it to air dry daily. I’m giving this 4 stars because of the price of the until. Other than it’s absolutely perfect.
