These gadgets are WONDERFUL! Useful in so many situations - I have had them for years, keep one in the car, never go travelling abroad without one and have given them to many of my friends and recommended them to many more. Use them when peeing in the countryside, on the edge of roads, in dirty public loos, foot-pad loos still found on the continent, and terrifying foreign loos (star occasion was a long-drop loo in China which was just a plank with holes at intervals.) Invaluable for those who (like me) have back problems - no squatting and then being unable to get up again!
Practice in the shower until you get the hang of it. Hurrah for the She-Wee!
