Dyson's newly launched CameraJet electric toothbrush, priced at $499.99, is experiencing early reliability problems according to user reports. Several owners have noticed water entering the battery compartment when the device gets wet—a concerning flaw for a toothbrush that is meant to be used with water every day.

At least one user posted on the r/Dyson subreddit describing their unit breaking within 30 seconds of use. The water ingress issue appears to be the root cause of these failures, raising questions about the device's waterproofing design and durability for a premium-priced product.
