The sturdiness and light weight are a good combination.
Wish it could fold up, but if that feature would change the solid feel, then it wouldn't be worth it. We have very limited space to work in; it's awkward to release the suction cups, but again, I'd rather have them and it be a little awkward, than not have them and not be as solid. Safety over convenience.
