Love this portable version
on May 6, 2026
Posted by: AngiY
[This review was collected as part of a promotion.] This complements flossing very well and I love that this one is portable. I had an older and larger waterpik that was a chore to clean, but this one is much easier to upkeep. I just can't imagine using it anywhere but the shower though, the water gets everywhere. Definitely get one if you care about your oral health!

It's so lightweight, yet cleans very efficiently

[This review was collected as part of a promotion.] Great lightweight water pic! It is so light weight you will forget what you are handling...and not at all messy like the "old school" ones we grew up on. I love the fact that I can charge it, place it in my purse, and take it with me, and it holds the charge. I feel better after a good teeth brushing, I feel fabulous after using my water pic. I would pay $$$ for this unit. I use a Rx mouth rinse in mine for extra cleaning & protection!

[This review was collected as part of a promotion.] I used this waterflosser and I am extremely pleased with the results. It gave me an incredible cleaning in my mouth. The installation is very easy and the best of all is the battery durability.

Easy to use every day

[This review was collected as part of a promotion.] This cordless water flosser is compact and convenient for both home use and travel. It feels lightweight in the hand and the cordless design makes it easier to move around compared to larger countertop models. The water pressure is strong enough to clean between teeth and around my crowns without feeling too harsh. I also like that it’s waterproof, so it can be used in the shower without worrying about splashing. The battery lasts well between charges, and the included tips are useful for different needs.

Love the extended warranty
on April 30, 2026

[This review was collected as part of a promotion.] I really like that this product has a year year warranty vs the one year that's become industry standard. Personally I used this ina addition to regular flossing and it worked well. There was pretty of power and one fill up was enough for two flossing sessions (morning and night). Also appreciate the long charge time which makes this easier to travel with. Highly recommend.
