Happily surprised by the power this has. It does a very good job cleaning between teeth.The only reason I did not give 5 stars is due to the button on the handle. You need to push rather hard to shut off the water flow. It would be better if it worked the opposite way by having the water flow when you push the button. Otherwise, very effective.
I bought this to replace the one I have been using for the last 10 years. I use it twice a day and it works great. It is a little noisier than my previous one.
My dental hygienist recommend I purchase this product to better flush around teeth, gums and crowns. I really like this because it's easy to increase pressure of water. Easy set up and storage.
