A Must Have Tool for Any Home Barista
Color: Black
I didn’t realize how much I needed this tool until I bought it, and now I use it all the time. It’s the perfect companion to my espresso machine and really helps improve my espresso puck preparation. The quality is great, it’s easy to use, and it adds more capability and consistency to my home brewing setup. I would absolutely recommend this to anyone serious about improving their home espresso experience.

Sturdy tool for improving coffee distribution
Color: Black
For those who do not know what this tool does:
The Weiss Distribution Technique (WDT) is a distribution method for espresso making, by which you use the tool to stir the coffee while it sits in the portafilter. You should use a portafilter funnel of the same size to avoid spilling grinds. The stirring action breaks up clumps and evens out the density of coffee within the puck. The result is reduced channeling and more even extractions.
Who needs this tool:
Those without a conical burr grinder, where the oil and variety of grind sizing may cause clumping, will benefit from this tool. Those with a decent conical burr grinder will find minimal benefit from this tool. I'm using a Breville Pro and do not see a huge improvement myself, for example.
Quality:
The build quality of this tool is excellent. You can add from one to seven needles, with many folks saying three is the sweet spot for best distribution. I've been using it for over a month and none of the needles have bent. The stand is solid aluminum and well-made, but it doubles as a protector of the needles. I just clean with a quick rinse and a wipe before returning it to its stand.
Outcome:
I did not realize most of the info above until after purchase. So my puck is solid, the pull is clean, and my coffee tastes great with a Breville Pro. However, this tool has a minimal amount to do with that. It is a worthwhile tool for those with a lower-end grinder, especially non-Burr grinders, and it is aesthetically-pleasing and well-made, which is why I rate it 5 stars overall. It also is of good value compared to more expensive variants.

Top quality tool that improves espresso extraction
Color: Gray
Fantastic and easy to use. Stand sits on top of espresso machine and the WDT tool is always ready, no unscrewing. Upgraded from a screw-shut version and couldn't be happier. Comes with extra needles which I hope to never need. Easy to recommend

Makes a difference but maybe only to caffeine addled coffee snobs
Color: Black
I won't say that everyone urgently needs one of these. This is helped me up my game. Perhaps not absolutely necessary, but it noticeably reduces canalization and improves extraction. And it appears to have improved not only my espresso, but my pour-overs and my Mokapot (especially the Mokapot!). It's a little fiddley to assemble - there's sets of springs and needles - but once you get it all locked down, its very tight. There's a set of spares - I can't imagine needing them. The tool kinda sits in the weighted base, but it appears to stay put in my cabinet.
