In order to guarantee the best user experience, we tested about 80 different types of patches and chose the adhesive patch from well-known brand 3M. On top of this, we reduced the area of skin contact with the patch, designing a circular double-sided patch for the best wearing experience.
We recommend that users use the adhesive patches we provide, and that the device be worn in the environment of room temperature. We recommend it not be worn for more than 24 consecutive hours on the same spot. The patches provided with this product are hypoallergenic. However, if skin irritation occurs, stop using the iFertracker immediately and refer to your doctor for other adhesives.
