Best espresso upgrade or best prep tool? The clear winner depends on your goal

Display

There’s no screen on either product, so this category is effectively not applicable. If you were expecting a gadget with feedback, timers, or readouts, neither offers that. Winner: tie.

Performance

Product A, the Normcore bottomless portafilter, wins on raw espresso impact. A bottomless portafilter lets you see the extraction in real time, which is invaluable for diagnosing grind size, distribution, and tamping issues on a machine like the Breville/Sage Dual Boiler. With a 58mm format and a filter basket included, it directly affects the shot path and can help you identify channeling, improve consistency, and get more from a PID-controlled dual boiler machine that already has excellent temperature stability and pressure control. Product B, the MHW-3BOMBER WDT Tool 2.0, is excellent at breaking up clumps with its 8 SUS304 needles at 0.4mm, and that can absolutely improve puck prep. But it is a supporting tool rather than a shot-delivery component. Winner: Product A.

Build quality and design

Product A feels like the more substantial espresso accessory. Normcore has a strong reputation for practical, well-machined coffee gear, and a bottomless portafilter needs precise fitment, decent weight, and a secure basket seat to be worth owning. The fact that it is specifically listed for Breville Sage Dual Boiler models BES900XL, BES920XL, BES980XL, and BES990BSS is a major plus for compatibility confidence. Product B is also well thought out: SUS304 needles are corrosion-resistant, the adjustable range makes it flexible, and the magnetic stand with six replacement needles is a genuinely nice touch for storage and longevity. Still, the WDT tool is a simpler object by nature, while the portafilter has more mechanical importance and needs more exacting construction. Winner: Product A.

Battery life

Neither product is battery-powered, so this category does not apply. There is no charging, runtime, or battery degradation to consider. Winner: tie.

Price and value for money

Product B wins decisively on price. At £21.99, it is £38 cheaper than the £59.99 Normcore portafilter, and it carries a higher rating at 4.7/5 from 713 reviews versus 4.4/5 from 1865 reviews. That makes the WDT tool a very strong value proposition if your current setup already has a decent portafilter and basket, because puck prep is one of the cheapest ways to reduce channeling and improve consistency. However, value is about impact as well as cost. If you are using a Breville/Sage Dual Boiler, the portafilter can unlock better visual feedback and a more serious espresso workflow, which may justify the extra spend. Winner: Product B for pure value, Product A for upgrade impact.

Game library/features

Since these are coffee tools, the equivalent here is feature set. Product A’s key feature is the bottomless design itself, plus the included filter basket. That combination is more than cosmetic: it provides diagnostic visibility and a ready-to-use setup. Product B offers a surprisingly rich feature list for the money: adjustable spacing, 8 fine 0.4mm needles, SUS304 stainless steel, a magnetic stand, and six replacement needles. It is more feature-packed in a practical sense, but those features are all aimed at one narrow task: distribution. Winner: tie, with Product A better for espresso workflow and Product B better for puck-prep convenience.

Overall user experience

This is where the decision becomes clear. Product A delivers a more dramatic and memorable espresso experience, especially for owners of the Breville/Sage Dual Boiler series. If you’re chasing better shots from a machine with strong fundamentals like a dual boiler, PID temperature control, and a capable 58mm ecosystem, the bottomless portafilter gives you both better feedback and a more premium workflow. You will see the extraction, learn faster, and likely improve your technique. Product B is easier to recommend as an everyday helper: it is cheaper, highly rated, and extremely effective at making a fluffy, clump-free puck before tamping. But it won’t change the machine experience nearly as much as a bottomless portafilter. Winner: Product A for the overall espresso journey, Product B for budget-conscious prep.

Overall summary: if you want the single best purchase for improving your espresso setup on a Breville/Sage Dual Boiler, buy the Normcore bottomless portafilter. If you want the best low-cost tool for better puck prep and you already have the rest of your setup sorted, the MHW-3BOMBER WDT Tool 2.0 is excellent value. The portafilter is the more transformative upgrade; the WDT tool is the smarter budget buy.
