Rode a NiVinci bike with a different shifter, it looks like it is just a sticker over the existing shifter's gear indicator. People must have been getting confused which way is harder or easier. I also got a one question survey on whether rotating to A is harder or easier. It still doesn't change the fact that it shift opposite from the Nexus shifter.

I do notice that this shifter has less grip, thus when it is wet, I sometimes have trouble engaging in the gear I want.

Here's the weblink to it:
