Hello,
The lifespan of the electrodes depends on several factors: Location on the body, type of skin, type of programme used (very soft which does not move much, or stronger, with more pronounced shaking), size of the electrodes, ....
I would say that the electrodes hold up well for about 20 - 25 minute cycles. After that, they start to come off and you have to change them. Unless you place them in a place (elbow or knee) where you can use a sleeve, which allows you to use them even longer. Such a sleeve is available from Galaxus
Compex Haltebänder für Wireless, 4 Stk. But I think you can use any type of sleeve that holds the electrodes well in place.
There are also "generic" electrodes that are cheaper than the original Compex ones (on Amazon for example), but I haven't tried them yet.
