We only use tried and tested Medical Grade Hypafix Plaster for our Overlay Plasters. They are Hypoallergenic, safe for all skins and are also quick drying. Hypafix lasts 4-7 days on average, and longer if you use our application method. It is always better to apply your Plasters 2 hours before or after bathing, showering or swimming. Skin should be completely dry and properly prepared before applying a Sensor or a Plaster
ALL OUR AIDEX OVERLAY PLASTERS HAVE THE CENTRE CUT OUT TO SNUGLY FIT AROUND THE TRANSMITTER then also has the centre piece to perfectly stick onto the Transmitter as well.
