Dentist suggested using a waterpulse. I didn't want to spend a lot in case I didn't use it. It's agreat price, good size, when water runs out on lowest speed, I know I am finished. I like it.

The package arrived in perfect condition, bubble wrapped for safety. The Waterpulse is light and easy to hold. The package also has a small booklet with simple instructions and illustrations that are fairly easy to understand. There is also a 1 page note with just the installation instructions with a few diagrams in case you don't want to time to read the entire booklet before starting to use. The package has the first set of 3 AAA batteries which are to be inserted as indicated at the bottom of the waterpulse. It's easy to unlock the battery holder, put in the batteries and lock in back again. Then there are 2 pik's provided in separate plastic wrapper and I took the finer one to insert at the top, you turn it till you hear a click and it is locked into place. After that you pull out the water reservoir (which is the transparent portion on the Waterpulse) and open the nozzle and pour warm water into it. Its a small reservoir so make sure that you fill it well and it does not leak from the other side. After that you need to fit it back into the Waterpulse and click it into place. After that you can turn the switch and test the water pressure. There are 2 settings for it and it will be better to start with the low setting, also keep it in your mouth when you turn the switch on, otherwise the water will spray all over the bathroom. I find it easier to use it while in the shower. It is cordless and very easy to handle. Also the water reservoir uses up the water within 1 minute so you have to be quick to get the flossing done, or fill the reservoir again. The first time I used it, I had to fill the water reservoir twice to floss effectively, but I did get the clean feeling of having successfully flossed. 😁 It may take a few weeks to get used to it, but I think this will certainly change the old mode of flossing which was cumbersome and very messy. I highly recommend this Waterpulse Cordless WaterFlosser 👍👍

Update after a month or so of use.
I use the higher setting now and my oral health is better than ever. My dentist said good job on flossing and I told her I haven't been. Then I told her I got a waterpulse 😉 Still on first set of batteries so going through a crazy amount doesn't seem to be an issue for me, but I'm the only one in my house.

A little akward and still getting the mess control down but works great. I only use low setting and it does have some force. Seems to be working great but will find out in a month or so when I go back to the dentist.

After having multiple rechargeable Waterpulses, all of which start losing their punch in a matter of weeks regardless of recharging techniques, this battery operated Waterpulse will hopefully end the cycle of trashed Waterpulses. Moreover, this battery operated Waterpulse has better performance on the low setting than the rechargeables on the high setting, not to mention also much quieter. The water reservoir is small, but this is no particular problem refilling to complete the job. It's also more compact making it more suitable for travel.

Be sure you use warm water, cold from the tap hurts (and I don't have sensitive teeth or anything).

The waterpulse is pretty effective. I got it because my floss smelled like death after use, and didn't seem to improve with more flossing. The first week of use I could smell the smell when using the waterpulse, but after 3 days the frequency of the smell was decreasing, although I'd still hit a pocket on occasion and it was pretty gross. By the end of the week the smell was gone from all the pockets, and after flossing the floss didn't have any smell.`
