I have a current model of Gaggia Classic Pro, but it came with an aluminum shower holder diffuser, which has rusted. When this replacement arrived, I had some reservations that it was a Gaggia branded part - there is no indication on packaging or on the hardware itself, that it is. Honestly, I still don't know, but it does fit perfectly, and is an upgrade over the aluminum original in terms of heat retention. It works exactly as it should, and I feel that it may even distribute the water a little better than the original (could be imagining that). I'm happy with this replacement.
