Reservoir inadequate and power too low. Hard to fill.

Hello Moe Joe - We are sorry that you are not impressed with the WP-450. It is designed small as it is intended more for those who travel and for those with little counter space. Some users may find it necessary to fill the reservoir more than once. Although the pressure is not as strong as our counter top models, it is still effective. 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.
Really liked how clean it feels when done being used. Not too much of a learning curve but is a little tricky at first to learn how to avoid shooting the water unintentionally. Love that there were four different tips included, even if I mostly just use the plaque seeker. Nice long life battery that lasts all week. Only downside is that the water tank is small (well..it is portable/travel size & cordless so I get it) and so you need to fill it about four times for a whole mouth cleaning on the low pressure setting and maybe 5 or more when using the high pressure (I don’t use it like that all the time though cause it’s pretty forceful).
I've been using them for years and they last a long time. I get great results during my dental visits at the dentist.
I would recommend this to a friend!

Hello Jaxjazzy1- We are happy to hear that the product has helped to improve your oral health! We appreciate your feedback and will make sure to pass your comments on to our Product Design Team.
Portable and readily available when needed. Ideal for travel and short-term out of home stay. After a day or two, I noticed that I had to keep it charged. Overall, well worth the price. Even my dental noticed the improvement.
