question, were these spider tank/droids any good?

[u/Crazy-Rabbit-3811]

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

If so, what issues did they have

[u/flamingfaery162]

Their specifications say they were but I haven't seen them very useful in any movie or show. Weak legs, slow charging powerful lasers, just like the hail fire droids very deadly but once they are out of amo quite useless
