Review on 💦 Waterpik Radiance Electric Countertop Dental Oral Irrigator: Ultimate Water Flossing Experience with 7 Tips by Stephen Mitchell

Another reviewer noted that it sometimes takes multiple button presses to get an answer. I also had this difficulty. I have contacted support. They explained that sometimes the handle needs to be re-synced to the base. I followed their instructions and haven't had any problems since. Here are the steps (Note: the device is connected to the network but not turned on). 1- Remove the water tank and turn the device upside down. In the lower right corner of the image you will find two rectangular sections. 3- Find a small round hole with a (batteries?) symbol next to it. 4- Insert a paper clip into this hole and push down. 5- If the two blue lights start flashing at the same time, the button has been reset. 6- Press the mode button on the handle to turn off the light; Turn the device over and restore the water tank. Tip - If I keep the pen within 6-8 inches of the base I have no problem. Regarding the irreplaceable CR-2032 battery. I also don't understand why the stylus was designed to need to be replaced when the battery dies. However, as far as I know, the device is insured for three years, which means (as I understand it) that if the battery dies during that time, the stylus will be replaced under warranty. Also CR-2032 is the same battery. Used in the key fob for my car. I've been using the same battery for over three years and it gets used a lot more than my Waterpik. Who knows, maybe the company will do a redesign if I have to replace it. I've had four Waterpiks so far and this is my favorite. (By the way, full disclosure, I didn't buy this unit from Revain when I got one of those deals from the manufacturer on Black Friday.)
