Hello, Ry! The LX has worked well for my purposes. However, the Mac + bracket is at or over the weight limit for the LX, so I suspect if I were moving the arm more than I do I might run into some problems. I had to tighten the arm quite a bit to get it to stay in place: it still moves and can be adjusted, but if I were moving it several times a day, it might develop some problems.

Hopefully this helps in your assessment…
