At what point did the Technodrome not seem like a threat anymore?

So at what point the Technodrome no longer seem like a threat? It's kind of hard to take it seriously to be honest, or at least it becomes harder the more you watch the show.

Now in theory a giant death machine from another dimension should be the most awesome thing ever, and I guess to many of you it was. However, considering it was in an almost useless state throughout the vast majority of the series, it does eventually no longer seem that great. Even when it is being used it seems like it could be defeated rather easily. And the design, giant disco ball with an eye on top, certainly does not help it's case.

So when did you realise it wasn't all that great?
