I've used an inductive Posidon oral irrigator since 2016. I'm well satisfied with the performance of the product. I would think that there should be a method for replacing the batteries short of replacing the body assembly including the motor, pump and plumbing. However, your policy of body replacement may be the most effective in the long haul. Thanks for your prompt and courteous help.
Good help from folks at TTP who recommended the replacement. Saved money and had fast service, The replacement is working fine.
My water pic irrigator stopped charging. The replacement irrigator was a great replacement. Just a reminder..don't too your old one until the new one arrives because you'll need your original water reservoir part..and any tips you already have.
Love your customer service and products! Thank you!
