I should have thought about this more - before I blew US$80 (incl. ship to Oz).
Easy to set up. Works perfectly -FOR THAT SPECIFIC TABLE HEIGHT! You raise or LOWER lower the DP table, you have to reset it! Yeah, I know - of course.
Edit: Good news and bad news...
Good: Finally worked out out to set it correctly - left side set perfectly
Bad: Right side stopped working altogether while I was setting it
Worse: Not worth the Oz shipping to send it back for replacement
