These are so easy to use and, really come in handy if you are out on the road and, can't squat . They work wonderful and, save on time too! No need to pull the pants down to squat and pee when you can stand and pee a lot quicker. No mess and, can use over just rinse and, walla your ready for the next use. I wish that I had gotten these long ago! Vacation's were always a booger to find a rest stop or, gas station that wasn't full and, you had to stand in line for awhile. With these you have no worried about that.
