Had a waterpik that was similar to this, but with 7oz reservoir that lasted ~45 seconds with PSI settings between 45-75. Imo this was not enough water to do even a semi okay job.

~10 seconds per quarter of your mouth. That's inside, outside, and the top/bottom side for all teeth or ~3 seconds for each of those sections in each quadrant of your mouth.

This one is has a 6oz reservoir with ~45 second so the pressure might be lower to keep that ~45 second mark. Their website doesn't list the PSI for this model WF-20. Yes it is a portable model for traveling, but if you want to do a decent job you're going to have to fill this up twice each time.

I would highly recommend a larger version for home use. I ended up with the Aquarius Professional model. 22 Ounces ~90 seconds of use time.10 to 100 PSI. Check ebay... $50 from multiple sellers.

Probably all the same give or take they just pulse shoot water.

I have some china factory brand which works fine, only downside is it uses a proprietary charging usb cable so I'd be out some additional cash or the thing is worthless if i lose that cable.

If you don't have one and looking to buy I'd recommend to buy but if you already have one and potentially upgrading... probably not.

Pardon my errors .. first comment on this app

I have used a couple of waterpik products. I've used their full capacity water flosser and very happy with it. No issues at all and it's been over 2 years of everyday us.
I can only speak for the waterpik but I've heard that bitvae is decent and affordable.
I do travel and I feel this unit will be a good buy
I hope my comment helps. Cheers

I use this model in the shower and it works well for my routine. There's no mess, battery lasts a few weeks, and I actually use it since it's convenient. I had a countertop one that just sat there unused before this.

I'm no connoisseur of water based gum cleaners, but the two pressure settings, usb-c charging cable, dishwasher safe tank cleaning is good enough for me to feel happy with this.

Fill it up halfway through.

I have an older AA powered version. One tank top, one tank bottom. It's not that big of a deal.

But then what do you do when you travel? I have the Aquarius too, but hard to fit on a carry on.

WP-663 Is what I got. Any of the WP-66# are the same series, just different colors. It actually isn't the "professional" model and I remember why. Only thing different is the knobs aren't in chrome which meant nothing to me so I went with the cheaper model.

https://www.waterpik.com/products...70/WP-660/

comparison between pro and non-pro models. I see the WP-66# models on amazon and walmart for $70 right now. I got mine a year ago so price might be a little higher now.
