WaterpikGenuine Precision Tips Replacement for Cordless Handheld Water Flossers (Formerly Classic Jet) Refill Heads Nozzles JT-450E, 2 Count (assorted colors)

I was gifted the Oral B iO electric toothbrush, and these tips work with this brush. I feel that they help fight tooth plaque and am very pleased with a more positive check up at the dentist's office.

So far, working well with my Waterpik.

These are the correct spray heads to replace ones the are damaged or lost!They are identical to the ones that came with the kit. They are delicate and can easily break when accidentally hitting an installed one with your hand.

I was concerned this wouldn't fit my old waterpik model but it fits just fine. Works perfect and I can get the usual water pressure from every setting.

Love these refills for my waterpik.

Will buy again

Like the “ like the blue light “ for anti bacterial treatment. Took a bit to get used to the different pulse speeds. Works well.

We are still wondering how a grain of rice made it into the prior nozzle??? But it did and blocked the flow of water. The Water Pic was making a strange sound when the tip was blocked so my wife (smart lady) turned it off and called me. Under a strong magnifying lens I could see the grain of rice. There was no way to get to it to remove it. Luckily the original kit had a spare. Replacing the clogged tip made it work again. But, now we had no spare - not good. These are the ones wife uses, so I bought them to have spares. Probably will never know how the grain of rice got in there. I'm a great believer in having a backup and these are "standing by" in case needed.
