Known allergic reactions

Among all E4 users (thousands) we have been reported with two cases of allergic reactions of light
intensity (few days of persistence). Those people were also allergic to other types of substances.
Please contact immediately our support team for any issue related to this topic.
During summer, the mechanical interference between the E4 band and the skin may cause the skin
to becoume itchy. This is not related to any allergy but if this happen we suggest to pause the use
of the device for few hours.
