I purchased this product because it's portafilter hole is 60mm - a diameter that fits really well 51mm portafilters on my bran new La Pavoni Esperto Abile. I wish the colour was more oak and less red-ish nevertheless it's a very snug fit and super functional for this espresso maker. There's another adapter ring included for those with larger portafilters.
I was dealing with Zhongshan Liangyuan Metal Products Co., Ltd. - Contact name: Sophia Xiong who understood my requirement and 2 weeks later products arrived with no import tax duty or VAT :)
