I find the strips easy to use and the colors are bright and easy to check. The strip is basically just a pen with the active part of the color at just one end. The strips are supplied as a bundle in a small plastic bag. I find it advisable to keep the bag of strips away from the sink or toilet as there could be an accident if water splashes or the bag falls. I don't usually urinate directly on the strips; I fill a small plastic cup and dip the strips in to try different brands of strips I have on the same pattern.
