This wireless Waterpik is easy and convenient to use. A few weeks ago the battery stopped holding a charge. I’d use it for less than a minute and it would be dead. Today I called Waterpik customer service and was advised to disconnect charger from device then hold in power button for 10 seconds then release. Alex at Waterpik customer service said that this would rest the battery. She advised to charge for 6 hours and report back to her whether that solved the problem. It did! Very pleased with the solution.
