Review: Good unit, easy to use and seems effective! - The device is very easy to operate. I fill the reservoir twice. Once for the bottoms and once for the tops. I have been using it on the children's mode to get my gums accustomed to the process. It's very easy to change modes. I remove the wand from the unit after I use it. One of the reviews I had read said someone had knocked his unit off the counter and the wand had broken off when It fell. The unit operates quietly and is easy to fill. I dry it off after use and leave the fill plug open and separate the unit to hasten the drying process. I am pleased with the product. It was an easy process to register the unit for the 2yr guarantee. The unit was very easy to charge.
Review: Love This Water Pick! - Love this water pick! Easy to use and very portable. I find it is better than flossing and much more efficient (very powerful spray). It took me a few days to get use to using it and not spraying water everywhere but it was well worth the effort. I highly recommend this product. So far, after five weeks of use, no problems.

### ⭐⭐⭐⭐ Lasted 11 months, which aint bad for what it is!
*by B***. on February 8, 2026*

Gonna give it 4 stars. Got mine 11 months ago almost to the day. Just 2 nights ago, seems like the battery is conking out. Just losing the pressure it once had. Worked GREAT the time it was working, so it was worth the $$ for sure. But now time for a new one. Will shop around and experiment with a different brand.
