The product is well designed, easy to fill, and hold. Learning how to use it without spraying water all over the bathroom was a process but now it all works fine. Happy with the product. But do have extra batteries because the ones inserted with the new product lasted about 2 weeks before failing.
The water flossing works very well. I only gave a 3 star rating because the batteries last only 3-4 weeks. It seems that the batteries are being drained even when not in use. Next time I will buy the rechargeable model.
