Charging problems

Would like it’s on its last leg and never know if it is fully charged. The light flashes all the time it is plugged in. Need to be constantly charged. I have a watch I only need to charge once a month, my sonic electric toothbrush only needs charging every 2-3 weeks. I would not buy this again.

WP-450

There's no way to add water through the small hole without spilling it all over the place. And it holds much too little water for an adequate flossing. I used the item 3 times and went back to manual flossing.

Hello SaveYourMoney- Thank you for taking the time to leave a review and share your feedback. We sincerely apologize for any inconvenience the reservoir has caused. This unit is specifically designed to be compact, making it ideal for travel and smaller counter spaces. However, it seems that a countertop model might better suit your needs. We offer a 30-day money-back guarantee and are here to assist you in finding the perfect unit for you. Please feel free to contact us at smreviews@waterpik.com or call us at 1-800-525-2774 for further assistance. Your satisfaction is important to us!

Poor battery life

Battery life was very poor. It stopped holding a charge several months after I started using it regularly. I replaced this rechargeable model with an AC powered one, which worked much better.

Not as good as the countertop model

A friend suggested I try this model because you can floss in the shower. I am not a fan of that and prefer the corded model. I have regrets.

There's still Food!

After flossing & brushing, I use my waterpik flosser, and there's still food in between my teeth! Easy instructions & easy to use!
