What is Reddit's opinion of Gibraltar Black Ball Beater for Cajon and E-drums?

From 3.5 billion Reddit comments

I have the iron cobra double pedals on my Roland TD-17 and I used these Gibraltar beaters to help with noise reduction. They should help this issue and they really cut down the noise, but have the same results for E-drums as a normal beater.
