Will change the future of spray bottle usage. Nothing is more annoying than getting low on your liquid while spraying window cleaner or some other product and the bottle stops spraying suddenly. You know there is plenty of liquid in there. But you have tilted the bottle and now the liquid is no longer able to be pulled through the suction tube. Introducing NEVER DRY SPRAY BOTTLE. Get all of the liquid from that container and never run dry again.
