My son has fought good hand position since day one of piano, and he's been at it for several years now. I got these and he instantly started playing with good hand position and has kept it up even when not wearing them. 10/10 product, works exactly as you want.
I'm taking one star because the color is advertised as muted gold but is actually a greenish metallic color. I'm a 3d printer myself, and I know real gold silk PLA exists. Please offer that instead of this color, or call this color Green Metallic
