The water flosser does a great job cleaning around the gum and between teeth. Much better than string flossing. Would be better if it held more than 45 seconds of water, but then it would not be very portable. With some practice I have managed to accomplish good cleaning in 45 second most of the time.
I purchased the Waterpik Cordless Advanced Water Flosser to replace an earlier model from Waterpik. I found the newer model to be easier to use. I like the charger much better than my previous model. It is very effective with cleaning by the gum line and in between teeth.
The only downside is I wish that it had a bit more water capacity, but that is only a small inconvenience.
I recommend this product to anyone looking for a quality water flosser!
