Review: Surprisingly, this basket significantly improves shot quality - I am extremely amazed how much of a difference the basket makes in my setup. I have a Casabrews Ultra espresso machine that I have been trying to dial in for 2 months. The shots have been decent using a Kingrinder K6 and freshly roasted beans but something was always off. With my bottomless filter, the shots formed a black "rat's tail" in the beginning and only at the end of the shot was there froth that turned into a thin layer of crema. I have been experimenting with dose, grind setting, temperature and different beans etc. and the results have always been the same. My first shot using the IMS basket immediately showed a brown, frothy rat's tail and generated a good shot with good, lasting crema even though the shot ran too fast. Next time I'll grind finer and expect to finally get out of the machine what I wanted. It's amazing that the basket can make that much of a difference. When I fill it with water, it runs through at approximately the same rate as with the stock basket. But, holding it it's apparent that the bottom of the basket is much thicker than that of the stock basket. I assume that is the factor that makes the difference. For Casabrews Ultra owners, I highly recommend this basket but there is a caveat. One review here states that the basket is too tall when used with the stock portafilter holder -- I have not confirmed this. I use this replacement bottomless filter holder https://a.co/d/0bpO2LWA with no issue. This basket will probably help most espresso machine owners to pull a better shot but especially those with budget machines that came with a low quality basket. Remember you will have to dial in your grind size again and most probably have to go finer because of the thicker bottom of the basket that makes the holes deeper.

The quality is top-notch, just what you’d expect from IMS, and it works like a dream with my Gaggia E24. Sliding it into the group head is smooth, removing it is even smoother. No more stuck pucks—they pop right out like magic. I rinse it with hot water and dry it after each shot, and my espresso has never been more consistent. I usually dose 16g (sometimes 17g) with a stainless steel puck screen, and it pulls perfect shots every time. Might be tight for 18g with the screen though—haven’t tried it. If you’re using a Gaggia or similar machine, this basket’s a no-brainer upgrade. Highly recommend! ## Frequently Bought Together - IMS Competition Convex Filter Basket for bottomless 58mm portafilters (20g) B702TCH26E - Normcore 58.5mm Coffee Tamper V4 - Spring-loaded Tamper with 15lb / 25lb / 30lbs Replacement Springs - Anodized Aluminum Handle and Stand - Stainless Steel Flat Base - Normcore 58.5mm Puck Screen - Lower Shower Screen - Metal Coffee Reusable Filter for Espresso Portafilter Filter Basket 58mm - 1.7mm Thickness 150μm - 316 Stainless Steel --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/458140317-ims-competition-convex-filter-basket-for-bottomless-58mm-portafilters-20g](https://www.desertcart.us/products/458140317-ims-competition-convex-filter-basket-for-bottomless-58mm-portafilters-20g) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-12*
