Review: Inexpensive, compact, effective - Inexpensive, compact, effective and very easy to fill - this is a very good travel water flosser. Good design. I’d choose it again.
Review: Great for travel - I didn't want to take my big water flosser on a trip to visit family so this was perfect - kept it in my backpack so I could clean my teeth on the plane and get my Invisaligns in without brushing - I could wait till I was off the plane for that. I did have to refill it once to get all my teeth inside and out thoroughly but that is minor given how nice and compact this is. The charge lasted the entire 6 days I was gone and I used it 3-4 times a day.

### ⭐⭐⭐⭐⭐ Inexpensive, compact, effective
*by M***N on January 22, 2026*

Inexpensive, compact, effective and very easy to fill - this is a very good travel water flosser. Good design. I’d choose it again.

### ⭐⭐⭐⭐⭐ Great for travel
*by H***W on January 9, 2026*

I didn't want to take my big water flosser on a trip to visit family so this was perfect - kept it in my backpack so I could clean my teeth on the plane and get my Invisaligns in without brushing - I could wait till I was off the plane for that. I did have to refill it once to get all my teeth inside and out thoroughly but that is minor given how nice and compact this is. The charge lasted the entire 6 days I was gone and I used it 3-4 times a day.

### ⭐⭐⭐⭐ Works well but needs improvement.
*by D***I on January 23, 2026*

This water flosser works well and is totally portable for travel if needed. But, there are a few things that need improvement. First, the power button is located in a terrible place, meaning that if you aren't careful and pick up the device with your fingers in the wrong position, it will turn on and squirt water everywhere, possibly on your face or in your eyes. This leads me to a related issue: there is no lock or safety button to disable the power button, so it's always ready to fire off, even when you're trying to fill the reservoir with water. Overall though, with these two flaws, the flosser does its job, and its size and weight are a huge plus.
