Is the KOFIKOFI Bottomless Portafilter worth buying? Yes — if you own a compatible machine and want a £28.89 upgrade that helps you diagnose extraction issues in real time, it offers strong value, especially at its all-time low price.

The first thing that stands out is how specific this accessory is: it is a 51mm, 3-ear bottomless portafilter made for the DeLonghi Dedica EC680 and EC685, plus SMEG ECF01 and EUPA machines. That narrow fit is both a strength and a warning. If you have one of the supported machines, the appeal is obvious: the naked base lets you watch the flow column and spot channeling, blonding, or uneven extraction as it happens. For anyone trying to improve shot consistency, that feedback is much more useful than a standard spouted portafilter.

The construction is also aimed at the enthusiast end of the market. KOFIKOFI lists a 304 stainless steel handle head, a 304 stainless steel puck screen, and an original-designed anodized body. That matters because espresso accessories live or die on fit, finish, and repeatability. The included puck screen should help distribute water more evenly over the coffee bed, and the stainless steel basket is a practical touch for durability. The basket is described as a two-cup capacity and can be replaced with a basket of any depth, which gives you room to tune your dose and recipe rather than being locked into one setup.

Performance-wise, the bottomless design is the real reason to buy this. It does not improve the machine by itself, but it makes your own technique easier to evaluate. If your grind is too coarse, your tamp is uneven, or your puck prep is inconsistent, a naked portafilter will show it immediately. That makes it especially useful for Dedica owners who are already experimenting with grind size, puck prep, and basket changes. The trade-off is that it is less forgiving than a standard portafilter: sloppy prep will be exposed, and there is no spout to hide issues. That is a feature for learning, but a frustration if you just want a tidy shot with minimal fuss.

Build quality looks respectable for the price. At £28.89, it undercuts a lot of espresso accessories that sit in the £30-£40 bracket, and the current price is also the all-time lowest recorded. The 4.3/5 rating from 99 reviews suggests most buyers are satisfied, though not universally delighted. That rating is decent rather than exceptional, which fits a niche accessory: people who buy it for the right machine and the right reason tend to like it, while buyers with the wrong expectations are more likely to be disappointed.

Compared with the listed alternatives, the KOFIKOFI is not competing with storage canisters or scales on function, but the pricing context is useful. The Airscape canister is £51.99 with a 4.7★ rating, the KC Kitchen & Co. airtight tin is £25.95 with 4.6★, and the Maestri House Mini Coffee Scale is £35.99 with 4.4★. Against those, the KOFIKOFI sits in the middle on price and slightly below the scale on rating. Its value comes from specificity: unlike a general-purpose canister or scale, this is a machine-part upgrade that directly changes how your espresso is extracted and evaluated.

The biggest warning is compatibility. KOFIKOFI explicitly says it only fits Delonghi Dedica EC680 and EC685, SMEG ECF01, and EUPA, and that it does not fit DeLonghi EC9335, EC966, or EC9115. That alone makes it unsuitable for anyone who has not checked their machine carefully. The other limitation is that a bottomless portafilter is not a magic fix for poor espresso. If your grinder is inconsistent or your puck prep is weak, this tool will reveal the problem rather than solve it.

Is the KOFIKOFI good value for money?

At £28.89, yes — provided you own a compatible machine and want diagnostic feedback from your shots. The fact that it is currently at its all-time lowest price makes the timing particularly attractive, and the 15% saving versus the £33.99 RRP improves the case further.

How does the bottomless design help extraction?

It helps by exposing the flow column, so you can see channeling and uneven extraction as they happen. That makes it easier to improve grind size, distribution, and tamping because the shot itself becomes a visual test.

How does it compare to a standard portafilter?

A standard portafilter hides a lot of mistakes, while this 51mm naked design shows them immediately. That makes the KOFIKOFI better for learning and dialing in, but less forgiving for casual use.

What should buyers watch out for?

The main issue is fit: it is for Delonghi Dedica EC680 and EC685, SMEG ECF01, and EUPA, and it does not fit EC9335, EC966, or EC9115. Buyers also need to understand that the basket is a two-cup capacity and that a bottomless portafilter exposes flaws rather than fixing them.

Is the KOFIKOFI worth buying in 2026?

Yes, if you have a compatible machine and want a £28.89 espresso upgrade with a 4.3/5 rating from 99 reviews. It is cheaper than many enthusiast accessories and more directly useful for espresso diagnosis than general coffee gear, but it is not a universal buy.
