I use this. Works fine. As noted, you need an allen wrench to set it up, but I have that in my toolkit anyway so not a big deal. If they legs were permanently attached and foldable, it would be easier to setup, but I like that they legs can be put/wedged anywhere in my front compartment on trips where I am space constrained.
Table is very stable and since you are using set screws to anchor legs and legs are angled, you can change their angle depending on ground you are setting up on.
