This was exactly what I needed for travel. It came as described and made it easy to keep up with my oral hygiene while away from home. It’s compact enough to fit in a travel bag without taking up too much space, and I plan to keep this as a permanent staple for trips. Setup was simple, and the instructions were clear and easy to follow. It charged quickly, filled without any hassle, and the different water pressure settings felt just right, not too weak and not too intense. My only small critique is that the attachments don’t have any color-coding. Since my wife and I plan to share the device (with separate tips), it would’ve been helpful to easily tell them apart. We’re currently using a sticker to differentiate, but that may not hold up long-term. Overall, this is a solid and convenient option for travel.

Easy to use and very portable!

Color: Green

I've been impressed that despite the size, it's got plenty of power. It's small enough to take on trips, but it still does a pretty good job of cleaning between my teeth. I've been using the large one for years, but this has replaced them. There are a few different settings, which is handy if you have sensitive gums. I've found it pretty effective and easy to use. The water tank expands, which is a cool feature, and you can store the attachment in the top making even more compact. While it might not be as powerful as the bigger models, it's been a nice addition to my daily routine, especially when I'm traveling. It's convenient, simple, and works well. I recommend filling from the top hole and leaving the bottom hole open to help dry it out when finished. Overall it's been terrific.

Will not charge after 1 month

Color: Pink

Liked this product, compact, good water pressure, easy to travel with, but I just tried to charge it for the 1st time after about a month of use and it will not register a charge. I've tried a bunch of different cables. It's just a hunk of useless plastic now and there's no way to contact the seller without leaving a review, which was not my preference.

Very Strong Flosser! Works great!

Color: Green

Really strong flosser! There are multiple settings for flow type. You may want to reconsider if you have very sensitive gums. The irrigation is pretty strong. It does get all the stuff you thought you flossed away, out of your teeth, gums and mouth. Good battery, it lasts for weeks to maybe a month and a half with daily use, up to 3 months longer before recharge, if not using everyday. I've tested out both scenarios, while still using a regular string floss daily.
