Review: Quality water flosser - It is easy to use and very effective. I use it in the shower because water does get everywhere...but that is the nature of the product.
Review: Powerful Flosser and Holds lots of water - I have used a water flosser for years but the brand I used was no longer offered for sale. I tried the big brand name flossers and was not too impressed because they didnt hold enough water and also the pressure was too weak. MySmile LP221 holds quite a bit of water and the pressure is very strong making it easy to get a good floss of your teeth. I found what i was looking for and and am a happy camper. You cant go wrong with this flosser.

### ⭐⭐⭐⭐⭐ Quality water flosser
*by T***2 on April 17, 2026*

### ⭐⭐⭐⭐⭐ Powerful Flosser and Holds lots of water
*by E***D on April 15, 2026*

I have used a water flosser for years but the brand I used was no longer offered for sale.

### ⭐⭐⭐⭐ New Model - Good vs Bad (Poor Customer Support)
*by J***E on February 12, 2026*

The MySmile flosser I bought three years ago quit working. I emailed customer support and received no answer. I purchased this new model and the motor runs smoother, the digital screen is better, and it holds a charge better. The only thing I do not like with the new model is they removed the small trap door on the side to empty the water and no way to air it out and avoid mold without taking it apart, but I discovered that they have a UV feature that cleans out the bacteria from the water tank which is very cool. I have had these in the past that got moldy inside. The part I still struggle with is turning the unit off without spraying water all over the bathroom.
