    I never owned a waterpik because I thought it wouldn't be worth the expense but I was wrong. The pik does a better job of dislodging food between my teeth and does a good job of stimulating my gums.

    It’s serving it purpose of keeping floss and pics out of the shower and missing the trash can. House with teenagers today.

    Had an older version of the water pik - it no longer held a charge. The new water pik, recommended by my dentist, works exactly the way it should.

    Works great for a child who doesnt brush very well and had braces. Does kinda get water all over, but that's the fun of it.

      Hi Roxy - Happy to hear you're enjoying the product. The Cordless Plus model does not come with an indicator light. We recommend charging the unit for 8-10 hours after every 6-8 reservoirs of water.

  • Great floss

    Does a good job, but only wish the reservoir was a bit larger to hold enough water to not have to refill (even if only 50% larger).

    This is a good unit. It does spray water a little bit more than I would like but it is not bad. It definitely does get what's in between the teeth.

    just kind of cheap quality. Seems the water stream could be harder to get all the particles. I should have reviewed others.

    This was recommended by my dentist, who suggested using it in the shower to avoid getting drenched. It works well and I hope will result in a good dental checkup in a few months.

    This is perfect for travel, but doesn't hold a lot of water. Noce that it also doesn't take up a lot of space.
