Thanks for your review and glad the product works well for you.
The absorbency is based on ISO testing in a lab. This is what is termed maximum capacity which assumes that all parts of the absorbent pad are used. Also that the flow of liquid into the pad is spaced out over time.
This is unlikely to be the case in real life as many people don't have that constant, slow liquid flow nor do they lie on their stomach, then their sides then back then stand up etc as is envisaged by the full use of the pad.
So depending on each persons use and flow they will have a 'working capacity' for the pad.
The point of quoting the ISO capacity is that it gives users a context of how one pad may compare against another for example the Plus vs the Super. We felt this was more appropriate than the typical industry measure of 'drips', which is totally meaningless.
The advice provided by our Continence Nurses is that pads should be changed regularly to avoid causing damage to one's skin so even if a pad could hold 2litres of liquid that would equate to about 8-12 full bladder voids and that would be very unhealthy for any user to have on for that length of time.
