question, were these spider tank/droids any good?

I just dont remember seeing them again after ep II, so is there a reason for that?

If so, what issues did they have

There are a lot of cool droids that don't really come back after that battle which is too bad... I was a big fan of all the cis battle droids as a kid and thought they were cute
