Which type of pad is known to be easiest to remove and replace?

The push-on pad is considered the easiest to remove and replace due to its simple design, which typically involves a straightforward mechanism that allows the pad to be easily snapped on or off the frame. This allows for quick changes without the need for any additional tools or hardware. It is particularly advantageous when a user needs to frequently change pads, as it minimizes the time and effort involved in the process.

In contrast, screw-on pads require the use of a tool to tighten or loosen screws, making them more time-consuming to replace. Twist-on pads may also involve more complexity in getting the alignment correct, while clamp-on pads can be more secure but often require adjustment and can be less convenient to change. Thus, the push-on pad's design prioritizes ease of use, making it the most efficient option for frequent replacements.
