Although we really want them to be used for full incontinence (and this is definitely in our long-term plans), they can only be used for light bladder leaks at this stage. The smell & viscosity of urine and blood is different. We're hard at work all the time in trying to figure out how to replace disposable adult diapers so that people with leaks can also have a more dignified solution. We'll get there, but we're not there just yet... Watch this space!
