I like the product and it does what it is supposed to do. I wish the reservoir was a little bit bigger and that the unit itself was a little more ergonomic.
User friendly. Handles well in one's hand. The water storage is rather small. I run out of water before the job is done. Otherwise, I'm pleased with the item.
My mouth always feels fresher after use. Sadly, the power button is placed where the device goes on and/or off when you least expect. That means spraying water all over your face, sink, and/or mirror.
