Sumo springs bump stops

[Nightbrew]

I'm not seeing any info or feedback on the bumpstops from sumo springs international. Does anyone have any experience or info share?

I would go to their web site for info. I have seen many feedbacks on those springs on YouTube.

The main difference of SumoSprings that I like is their claim (not sure how accurate or true to description) is that it is a progressive type of bump stop rather than linear. Here’s the video:

I hope a first hand user of Sumosprings post here and provide insight if the engagement is indeed unnoticed. This is what I need ti know.
