Reasonable cost dental device (updated review)
I used this device for a few months to provide an accurate review.
First off, it works. Fill the bottom end section with water, snap in a tip, switch on and go. Easy to use, and the instruction set is short and simple, the result of a thoughtful adoption process. Very reasonable cost. Several heads are provided for you to select. And there are three settings to use: soft, normal and pulse. I did not find any benefit to the pulse setting as it seemed to cycle the water pressure lower than to normal repeatedly.
Several additional items worth mentioning:
1) The water pressure is modest. the lower pressure is made up for in more water delivery.
2) This device consumes water at a rapid pace. What this means is that you will need to either swallow or spill the water out of the side of your mouth at least twice during the 90 second cycle - while the unit is operating. Switch off during the cycle restarts the countdown. Water will accumulate rapidly in your mouth. You need to spill the accumulated water in your mouth with the unit on. If you remove it from your mouth you will have a mess around you.
3) The on-off switch is located on the handle toward the top. You will need to learn to not place your finger over the switch which abruptly shuts the device off. Conversely, if you like to swith off the device during the cycle to neatly spill accumulated water out of your mouth, you may find yourself attempting to find the switch push button without a tactile means of feeling for it.
4) The charge port has a small flexible grommet covering it, which might take a little while to find where it is located.
5) **This is my update from my original posting**: the duration of charge shortened over the last several weeks to the point where with the unit switched on, the lights are on, but the pump no longer works, meaning it died and has been trashed.

Decent water flosser.
This water flosser is a handy way to clean your teeth, especially when you're on the go. It's cordless and rechargeable, and it comes with different tips for various needs. The water tank holds enough for a full cleaning, and it doesn't leak. It has multiple settings, from gentle to strong, to get your teeth feeling fresh. While the tips might not be the most durable, and attaching the top can be a bit tricky, it's a great tool for keeping your mouth clean and healthy. It's a good alternative to traditional flossing, helping to remove bits and keep your gums healthy.

Works better than any of the others I've tried!!
Size: 1.5 Fl Oz (Pack of 2)
Not the greatest tasting but works so great that taste is irrelevant! Actually tastes like cinnamon not mint which is A OK with me! It is the best working and longest lasting of several I've tried. Finally! My search for something that works is over!

Taste is Weak Mint
Size: 1.5 Fl Oz (Pack of 2)
I tried another brand and liked it better. It was more minty than this one. It has a mild aftertaste. I can't tell one works that much better than the other. But it was at least something to spray in my dry mouth, so it worked.
