My 9100FX broke so I bought this to replace. The filter goes perfectly with it (I asked a question but didn't get an answer so I bought it to try anyway). to its lighter weight. I bought the FX thinking a pop up filter would be handy, but it turned out I rarely used it, didn't hold my hood up and was too heavy (the front is heavy to weld and weighs down my neck). I should have gone with it from the start. The only thing I don't like about this setting (not the hood itself but the filter) is that you have to turn it on manually. I'm used to my Millere Digital Elite so there is a "learning curve".
