Review on 🔧 Efficient Sanding with BOSCH RS035 Hard Hook-&-Loop Sander Backing Pad, Black by Marcus Akram

There is an H in a circle on the side of the product, I believe this indicates a hard lining. While the original pad that came with my ROS20VS has a circled M which probably means medium. While there was no discernible difference in foam hardness or hardness between the M and H pads with simple foam compression, I haven't received the (S) Soft pad yet, but I doubt it will make much of a difference. Will be updated after use if not up to expectations.
