IMS Precision Big Bang Filter Basket for 51mm Portafilters. 16-18gr. Compatible with Delonghi La Specialista, Dedica Espresso Machines.

It’s a very good basket and fits perfectly 51mm, you will need good quality and fresh roasted coffee and you’ll have a perfect expresso.

This filter Does not fit Delongie machine

Does not fit 51mm tamper and tools. Not sure how the have got this wrong and advertised as 51mm. Wish I would have read the reviews before ordering. All have the same issue hence 1 star. Also finish is really poor with really sharp and rough edges. Incredible how poor the quality is. Made in Italy means nothing nowadays. The cheap Chinese one that came free with my portafilter looks and feels miles ahead. This feels like it's made out of tin. Also the holes have scratched marks. Incredibly poor for the price.

Pour moi c'est la perfection. Beaucoup mieux que le nouvel E&B All in One que je viens de renvoyer!

I’ve been using this IMS Big Bang basket in my 51 mm portafilter (Delonghi/Sage), and it's quickly become one of my favorite accessories. What I love: Cleaner extractions – The unique hole pattern (tighter in the center, wider at the edges) really guides the water evenly through the puck. No more weird channeling or gushers. As one Reddit user put it: > “Hole patterns are designed to not coalesce and provide an even extraction.” Sweeter shots – Flavors are noticeably more balanced and sweet compared to my old stock basket. I didn’t expect this difference until I tasted it. Easy dialing – I found it surprisingly quick to dial-in. Even with different beans, I only needed a few adjustments before I was pulling great shots every time. Sturdy build – Made from stainless steel and built solidly, it feels durable and well-made . A few things to keep in mind: Dose & grind tweaks – A few others have noted that you may need to fine-tune your dose or grind size (a slight grind finer did the trick for me) . Fits similarly sized baskets only – Make sure your portafilter is 51 mm (or close). Mine fits snug with no wobble, but one user with a La Marzocco noted it fits loosely on a 58 mm basket —might vary by brand. --- 🔧 Bottom Line If you’re running a 51 mm machine and looking to step up your espresso game without spending a fortune, the IMS Big Bang is a smart choice. It consistently delivers sweeter, cleaner shots and makes dialing in your routine a breeze. It’s now my go‑to basket for daily use.

El filtro esta mal mecanizado. El diametro interior es algo menor de 51 mm, de tal manera que el tamper de 51 mm no entra bien y se queda atascado.

Che dire IMS una garanzia… cestello che utilizzo oramai tutti i giorni per la mia dedica suo 890 Con 18 gr di caffè fa uscire note che non trovo con altri cestelli merito dei buchi che all’esterno sono più grossolani per poi ridursi verso l’interno .. il caffè esce regolare e ben cremoso … prodotto molto valido

Size fit well,extraction is definitely 🔥 👌 the 51mm tamper is too small for the curve of this filter
