I much enjoyed it for the first week but now it won't sustain a charge. After being plugged in for 24 hours, it will work for only about 1/3rd of the reservoir before slowing and stopping altogether. Very disappointed

I bought this for my tonsil stones but even the less pressure option is way too strong. It made my tonsils bleed. Wish I could return but already used & packaging was thrown away.

Hello sgm1 - We're sorry to hear that the pressure from your WP-450 was too strong. If you need a water flosser that has a lower setting, we recommend a counter top model. Water Flosser products are intended for cleaning between the teeth and along the gum line. Water should not be directed into sensitive areas of the mouth. However, we do offer a 30-day money-back guarantee. If you would like more information, you can email us at smreviews@waterpik.com or call (800) 525-2774 for assistance.
