Great product. Great price.

And is easy to install with only a screw driver. The fact that the pause switch on the handle is the same as the original is important. A pause switch which requires you to press and hold is potentially dangerous and means you need two able hands to operate the flosser.

So far, so good. A quick fix.

Unlike the original handle, the on-off switch has been replaced with a button that must be held down to stop the flow of water. Not ideal. Otherwise, straightforward installation and appears to be watertight, so we'll live with it - for now.

Love it and will order again.

Works with less nozzle pressure, but it's not equivalent to the OEM. It's Oval and does fit the round holder on my Waterpik. Not a deal breaker for a less expensive replacement. The annoying thing is the button isn't an on off switch for water flow. It's Press to stop flow and hold to keep flow off. If you aren't holding the button in, it's on. On is the default state. Not fatal but annoying when you discover this operational difference by turning it on and discovering "Off" doesn't actually exist.The mechanism to change nozzles works but for lack of a better word it doesn't have the crisp operation of OEM.It didn't come with replacement screws. Which is fine. The old ones work and it's less waste. It did come with an identical looking filter to replace the OEM filter. Which is good.The deal breaker is that I'm getting less pressure out of the nozzle than OEM so I'm not at all sure my Waterpik is doing the job it's supposed to be doing with this replacement. If the pressure was the same I'd rate this a 2 but keep it. I'll replace it with an OEM one.My rating scale used here.5* - Better than OEM4* - Equal to OEM3* - Works but not the same quality as OEM2* - Serviceable with some help. (The on/off function)1* - Doesn't work for it's purpose. (Pressure too low).

I bought a while new machine then looked on Amazon and saw they had a replacement part. I returned the new having, bought this and just replaced it's. Saved myself a whole bunch of money. ** update **9/17/23-Handle started leaking. I'm now thinking about just replacing with another, possibly a different brand. I don't want to but another handle and chance it going bad on me after a few months.

It's a fine replacement when you don't want to buy a whole new waterpik. The thing works properly, but it doesn't sit in the Waterpik holder and keeps falling out when not in use.
