I have one on my Bix and I really enjoy. It doesn't seem as finicky as people often describe linear trackers in general.
There is one 1/2" bolt that secures it any armboard, and then it has 3 spike which you can adjust with an Allen wrench from the top. At first this did not seem very secure, but the base is very adjustable as such and very secure to the armboard. You can make fine adjustment very easily (as opposed to my JS Stancampiano linear).
I have a new table on the way and I should blog about setting up the MG1.
It has a free liquid damping trough available to a buyer after one year for free. The Alita pump is somewhat loud, but I put it in a wood box, and it sits in a cabinet on a piece of foam; can't hear it and though it heats up, it doesn't go Chernobyl.
