Bests & Worsts Reviews from Amazon

I have purchased waterpik ADA machines for about 10 years now. They need replacing about every 2-3 years or so. I have found the quality of the device r/t longevity of the device has drastically decreased. I purchased one just a year or so ago. Then motor quit. Purchased the present one this past July and it leaks constantly into the seat of the resevoir and out the bottom of the device onto and down the counter. And it hesitates to power on frequently. Please advise? I would request a return and refund but like I typed, I bought it just this July and have put up with the failings, but no more. Thank you.
