Incredibly satisfied across all areas here, amazing value, fantastic perfomance, rapid delivery. The level of luxury this brings away from 240v mains in incredible. I use it in my office as a matter of course now. Grinds 19g of beans very evenly and with low retention in approximately 2 mins.

Only mistake i made was not buying this earlier. Really makes a huge difference and now can see the extraction better and know how to fix it

After seeing some reports of portafilters ejecting from the Dedica line, I was worried about finding a quality portafilter that would fit correctly. However, after pulling multiple shots, it's clear this thing is well built and I have seen no evidence of ejection. It's heavier than the stock portafilter, made with better material, and looks great. I'm very happy with this.

Definitely better than the standard breville ones. Enjoying my coffee more now getting a perfect crema every time

Great! Its so easy and effortless to use, and I love the style.

Saw this discussed on a few forums. Was struggling to get a consistent pulled shot of espresso. Gave the screen a try and now have consistent well poured shots with no channeling.

Channeling issues are a thing of the past. The espresso pours beautifully, and the taste profile is noticeably smoother and richer. ​The build quality of these upgrades matches the machine perfectly, making the whole setup feel like a high-end commercial espresso bar right on my kitchen bench.

Works well and easy to clean.

Coffee Nerd Self-Levelling Tamper order arrived pretty quickly and it's pretty good too, thanks guys nice one...

I have been using a Breville DB for years, on my second one. Have always been able to get good coffees but had to constantly fiddle with grind and dose to stop channelling. Recently nothing I tried seemed to work. As soon as I replaced the stock diffuser and screen with this, every shot is perfect. Had to reduce the dose slightly, but every shot is way more balanced without anywhere near the amount of adjustment I used to have to do.
Highly recommended this and I really should have done this year's ago. For the price it is an absolute bargain.

The Bottomless Portafilter takes making coffee to the next level. Love the look and the performance. I feel like my coffee is tasting so much better.

Noticed the extraction on my Breville Dual Boiler wasn't pouring equally from the twin portafilter and discovered the plastic diffusion plate had a large crack so ordered a new plate, screen and seal. Received it the day after ordering so will definitely use the Coffee Nerd team again. Well done guys!

I was amazed at how it has transformed my machine! Excellent coffee.

Efficient delivery and customer service team was very communicative when I had a question about the product

Instantly improved shots! Then decided to upgrade shower screen and get a magnetic dose collar and needles to prevent channeling and I wish I did it years ago. If you’re going to spend decent cash on a machine these are a small further cost for big reward.
