Obsolence programmée du WF10 Pas démontable, pas clips’mais serti à chaud donc obligé de casser pour ouvrir. Pas de pieces détachées dispo Pompe bassée sur le frottement sur un joint qui une fois usé rend la pompe non fonctionelle donc pas d’eau qui sort. A fuir Une honte de vendre ce type de produit si on est ecoresponsable

12/12/2026 Waterpik has always had a reliability issue going back more than a decade. Most of the issues have been with the hand-held water flossers. They tended to stop working after a few months. This time, the corded version arrived dead on arrival. I have ordered a new one and I really hope it works flawlessly. Update 13/10/2026. The second unit arrived and has exactly the same issue. This is either a product batch or incomplete instructions. I requested a call back from the manufacturer and after a recorded voice message, the call was terminated by the manufacturer. It is clear that Waterpik should be aware of this issue. If they are not, then they are negligent and if they are, then they are worse than negligent. Time to look for an alternative manufacturer with a better approach to product reliability

I'm very disappointed in my new Waterpik Flosser Gem 5100. -The reservoir is difficult to fill completely; takes several attempts. -The button to remove the pik is difficult to use as well as pulling out the pik -Difficult to remove residual water remaining in the reservoir. -The rotating device moves easily if you're not careful. -The device is hard to hold unless one has a large hand. All in all I'm quite dissatisfied with your "improvements', especially with an $80 price tag. I really miss my old Waterpik which I had to discontinue using as it was starting to leak. I don't remember the model but the charger was magnetic. To sum up, this will be my last Waterpik flosser purchase. Will choose a different brand next time. L.O.

bought flosser device from official store online, did not work. new device - tank leaked, nozzle jumped out of socket from water pressure. followed their guides - nothing changed. so basically they send non working devices.

I purchased a Waterpik Promax device at my dentist’s recommendation to help prevent gum disease. I find the device unbearable to use: even at its lowest setting, it is painful, loud, and extremely uncomfortable. I contacted Waterpik to return the device, but the company refused to offer a resolution.

8 months and that "little engine" that could COULDN'T. It just died mid use. Without the purchase date I was stuck having to throw it away. hunk of junk.

Waterpik works well when new, but customer service is slow, creating challenges. I’ll use it because it’s effective and recommended by my dentist.

I had 2 Waterpik devices. First was Nano and it died after 2.5 years, after I bought more “heavy duty” device Waterpik ULTRA Plus WP-160 and it also died today after only 3.5 years. Kind recommendation DO NOT GIVE YOUR MONEY TO THAT COMPANY! Never again!
