I just wanted to point out that Oral B’s basic electric toothbrushes still range from $45-$80, so it’s not quite as cheap as you say it is. Your point still stands in its entirety. The only thing that makes this product different from the $45 model is the Alexa functionality, and taking that away makes it effectively not the same product.
Interesting that the screen has such an aggressive curve, but the scanlines and text box are relatively straight.
