I own the 8’x4’ Bora Centipede. Love it, as it’s lightweight, compact when not in use and fast/easy to put up. 8/10.
As mentioned, table height is a bit low for “proper” workbench height. Eg, with an 18mm top. Therefore, I have an 8’x4’ piece of sacrificial 90mm Celotex that I lay over the top. I have lots of spare sheet material kicking around, so currently I am laying it on top of a piece 11mm osb. Perfect height for me (at 6’1”).
I first used it on my Victorian property, which you might be forgiven for thinking had “flat floors”. However, using a relatively thick (rigid and flat) piece of insulation highlighted just how much a Victorian wooden floor can undulate. What a surprise! I was making large frames at the time, so I needed a decent flat surface, and found myself using packers to ensure all of the struts were providing support etc. Out of 15 struts I packed …6 or 7?
But if I’m not using it as an assembly table then I don’t bother using packers.
