Repackaged Costco item doesn't work
This waterpik is not from the Waterpik company, it was a repackaged Costco model. I know because the large unit didn't work (motor would not turn on) so I called Waterpik and they told me that model number was only sold at Costco, not from them directly or from Amazon's fulfillment center. Buyer Beware!
