Yes try it in the shower. With shorts on. You need to lean slightly, which is easier to try than describe. The extension tube is useful, and if you buy them together, you get a box, which makes it more discreet and solves the problem of having a damp one in the bag.
They are at their most useful when wearing bibshorts, especially when adorned with layers of clothing that you don't wish to remove and when faced with a mass of brambles and nettles
. I use mine indoors with the bibshorts as much as I use them outside.
The most difficult thing to get past is the feeling that you are weeing yourself, and it sometimes feels that there is some overflow, even when there isn't. When I am in practice, I don't have any problems, but it is tricky to use it again after a break.
I clean it with milton when I return home after a tour. I always carry one - there is a basic one in my nappy bag at work.
