I also use the “Fingers Over the Fence” method, most of the time. I have a push board similar to the one you made. Have made 100’s of them over the years. Never made a push stick. One come with my DeWalt table saw, but I usually only use it as a “Feather Board” while using my push board.

Looked at the “Gripper” online (I think that’s what it’s called) and was amazed at the complexity and cost. Guess enough people by them to keep them on the market. ???

No matter what one uses, it should keep one safe.
