wrong idem. will not fit my Portable Countertop Water Flosser, which I just purchased 2 months ago..
Best customer service! Expedited shipping. And my oral irrigator is a definite tooth saver! My dentist is now recommending them.
I got a flosser from Amazon and it only came with 1 head that I actually used and I lost it on a out of town trip. These are universal and work great!!! Highly recommend. Came fast too.
Nice to get replacements
I love my Poseidon water flossers❤️
