I was impressed initially with how thoughtfully designed this tool seemed. Depth adjustment is awkward (at the maximum depth, the needles in mine don't touch the bottom of my 20g basket), but the fact that it has a self-cleaning station, the needles and cleaning brush are all removable and replaceable, etc. is all great.

The problem, fundamentally, is that it doesn't work. After a few months of use, I realized that my shots were getting channeling regularly, and I even started to see visible clumps left in the puck after giving the tool a good 5-6 spins.

Even before that, it didn't speed up my workflow quite as much as I'd hoped. I still needed to use a dosing funnel when transferring grounds from my grinder, tap the portafilter to settle them, remove the funnel and use the Duomo (which would sometimes leave grounds on the edges of the basket or even spill some outside), then tap again, tamp, and pull. I would've considered it a slight improvement over the tedium of a manual WDT tool, except that the distribution wasn't actually working, and I've since gone back to just using a manual WDT that cost 1/10th of this device.

I can justify $200 for a truly excellent tool that I'll never need to upgrade again. But this is now a $200 paperweight.

Great feel, quality is really nice. Easy to use, packing it came in was really lovely as well.

Looked forward to expediting morning coffee workflow but did not get the consistency regularly with this tool. We were still ended up manually distributing before using the Duomo to ensure perfection. Overall, still happier with manual distribution techniques versus this tool.

Both my wife and I both make espresso but I do the dialing in as I'm the coffee nerd in the house hold... so this keeps everything consistent between the two of us so that her shots are as good as my shots. Also makes wdt less of a chore at 6am.

Ive had a number of WDT tools including a similar Normcore version with thinner needles that bent super quickly. This solves all the issues Ive had with other tools. Thicker needles that retract into the housing, all metal and fits perfectly over the basket. Consistent results every time and it matches my matte black Flair 58 and espresso tools. You get what you pay for. Endgame WDT for me.
