I am really pleased that this is a Malaysian invention. Amazing isn't it? Actually, since Malaysia makes many bathroom fittings products, we do have many other bathroom inventions. The exposed toilet flush, I think was invented by a Malaysian. He meant it to be a foot flush. The cost savings of installing one of these and its clean design made architect not think about its construction and installed it in many public toilets. It is sometimes too hard to push, as it is meant to be used by a foot, and placed at inaccessible place behind the toilet, discouraging those who can't not to flush the toilet. Sigh!
