Wearables company Fitbit hit back at reports that its new Charge device has caused skin irritations for consumers, stating that the issue is “not uncommon with jewellery or wearable devices that stay in contact with the skin for extended periods”.

The issue has gained a lot of interest because Fibit has form in this area, with problems coming after the release of its Force device. But the company said that the new cases are “very different”, due to the way that the products are constructed.

“While Force’s housing and band were held together with adhesive, which was determined to be the cause of nearly all allergic reactions, Charge’s housing and band are held together with screws, completely eliminating the potential for any adhesive to contact the skin,” a response from the company cited by Engadget said.

The latest issue has been put down to “sweat, water or soap being held against the skin under the device, or from pressure of friction against the skin”.

“We are encouraging anyone wearing an activity tracking wristband, regardless of the brand, to follow four key elements for maximum enjoyment: keep it clean, keep it dry, keep it loose, and give your wrist a break,” it continued.

When it was announced, Fitbit described Charge as “Fitbit Force reinvented”.
