This is my third water pick and the best so far. It is powerful. The toothbrush cleans better than that other brand. The change seems to last longer as well. I fully charged it and have left it off the charger to see how long it will last. It has been over a week and it still register fully charged.
This is my 1st water flosser. So far I am impressed. The motor is a little loud but other than that it's a good quality product. I was impressed it can with the accessories. Also this model has an electric toothbrush which works really well.
