Best water pick I’ve ever bought. It took a long time to get it, but it was worth it because it works great.

If it wasn’t for Lara I would not have ordered it. I’m so happy with that because of the speed of it and thank you very much. She’s the one that advertised for you guys.

I love my new water flosser. If you have doubts about trying it for bleeding gums, just give it a try. I have barely been using it for 2 weeks, and the bleeding has almost resolved.

I love my new water flosser. If you have doubts about trying it for bleeding gums, just give it a try. I have barely been using it for 2 weeks, and the bleeding has almost resolved. For context, I have been to several dentists in the last 5 years for this issue. I wish I had found out about this much earlier. I would have saved myself so many dental visits and, of course, money.

This irrigator holds much more water than my old model.

This irrigator holds much more water than my old model.
Even ful of water it seems much easier to manage as
I use it on both the top and lower teeth. bfore having to refill or add water. I also find this model easier to fill with
water. I am very pleased with the way this newer model
dislodges left behind hidden food. Left behind after I had
flossed my teeth with a tooth pick or regular flossing material. I do enjoy the WFP14 (New) irrigator.
