Less pressure than original item.
As other comments have said, this item doesn't provide the same pressure as the waterpik brand.<br /><br />Here's an update.  The item broke after I used it about ten times.  The photos for these "off-brand" water-pik replacements look the same from the various suppliers, so maybe they're made by the same munfacturer. I'll buy one from water-pik.  The extra $ I'll pay is less than more dental work.  I'll miss the return window by one day...  Lowered my rating to one star.
