I've succumbed to upgrading my lights since 2008, because I see better lighting available at lower cost. Better lighting has been worth it to me. And I expect I will upgrade again before 2022. If that involves a remote control, I won't mind.

I will change the light settings zero to one time during a ride, so changing on the fly would add little value to me. In fact, I can already do that, since all the lights except those on the seat stays are within reach from the saddle.

The memory function, so that the light starts in the desired mode, is handy. But my lights already have that, now. Even my 2008 lights had that.
