Thank you for that added information. Particularly interesting was the info about TENA For Men, which if the product is the same as the North American one, rates at 322 ml/11.3 oz (before leaks). This confirms a remark that these are "one shot wonders" (one shot being about 200-400ml). I've been lucky in the past pushing them way beyond this but I wouldn't do that now.
Even more annoying is the fact that TENA rates some products out of 8 drops and others out of 5 (TENA for Men for example) and still another out of 7! Some products have filled in drops on the package with the remaining empty (white) to show what level it is out of the maximum. But some products only show white drops. The reader is left to ask is this maximum? Or does it mean no absorbency? Or unspecified? Oh, I see- you're supposed to see the moon and assume overnight = maximum.
These are all TENA products: this shows 4/5 drops:

And this shows 0/8 drops or 8/8 drops depending upon how you see it. I suppose because of the background colour, they chose to use white drops (bad idea IMO).

So even within the TENA list of products you can't compare. I don't believe the first product being 4/5 is nearly as good as the 2nd at 6/7 drops. Yes agreed realworldic - the drops are totally useless!
