Great question, actually. We used the Rupes LHR21 here because that is the tool this particular customer uses but he uses our pads and compounds. He was looking for tips and information on how to use everything properly in order to obtain the sort of results he's looking for. There isn't a lot of sense in teaching someone how to use a tool other than the one they're using when, in fact, they already have that tool.
We have had people bring their own tools in the past, and even competing pads and liquids, only to determine they can get better results using our G110v2, microfiber pads and compounds after doing their own side by side comparison tests. And they have then left our training facility with a new G110v2, pads and compounds with them.
