Below Average
This leaves a steel aftertaste in my mouth, but that I could live with if it did its job the way I would like. I have several tongue scrapers  because I wanted to try out different ones. This is the last one I would go to, if I even use it. I have not used it for several months now. It removes almost nothing from my tongue. The only upside would be that it will last for many years but is that really such an upside when it does not do what it is supposed to? It is not too heavy but if you are flying, every little bit of weight counts, so you might want to think about that too.
