Wonderful WDT
I was not convinced this WDT would make much of a difference but it does. It is easy to declump espresso clumps. It is nice having the clever stand to store it in.

Looks great - Heavy base - Solid beautiful walnut handle - Replacement wires
This is a really nice looking wire distribution tool for espresso portafilter baskets. The base is a very handsome shaped solid aluminum that has a good amount of heft to it, so it won't easily get knocked over. And it's perfectly aligned with the ascetics of the solid walnut handle that makes this look great. The walnut handle, from what you can see in the photos, is made from about 7 to 8 laminated pieces of walnut; it's not just an end cap or veneer. It may not be a single piece of walnut, but it would be dimensionally stable and less prone to crack over time..
This distribution tool has 7 stainless steel needles that helps to break up clumps (see photos). I found it done a pretty great job but for the sake of preventing a mess, I found it was easier to stab the grinds from the top, and then produce a small tight circle, which I repeated a few times. I felt that if I were to just stir the fine grinds in big circles, it would have knocked a lot of them out of the basket. I'm sure with more usage, I would perfect the technique with far less mess. I later realized later that a dosing funnel would actually be very useful in preventing any mess and it would help keep the grinds in place (see comments below).
This set comes with an additional 7 needles, but as you can see in the photos, I left them in the packaging and did not get them out. I was curious how they were held in place in the handle, so foolishly I tried to remove the plug with my fingers and they slipped and I wound up pinching the needles. This happened before I took the photos, which explains why they are not perfectly straight and parallel to each other. I found this to be somewhat disappointing because they looked really awesome how perfectly aligned they were before I bent a few of them trying to remove the base.
My point of this warning is that the needles do bend if forced, so be careful with them. That is why I did not want to remove the replacements. To be clear, these are stainless steel needles that have a great deal of flexibility to them, and they do not easily bend, but they are also difficult to get perfectly straight again. My error was that when I was trying to remove the base, the pinching grip I was using bent a few of the needles when my fingers slipped off the base.
The base of the handle, in which needles are set, is friction set in to the handle. I was not able to remove it by using my fingers since it is that well secured. It looks and feels like aluminum which matches the base. My suggestion on removal of the plug, is to use pliers that are wrapped with a generous layer of tape to protect the finish of the aluminum plug.
Overall, I think this is a really attractive set. The handle really looks warm and rich in the natural tones and grains of the walnut. It is perfectly paired with a strikingly handsome aluminum base that has a good amount of weight to it so it won't easily fall over if slightly brushed. The needles do retain a residue of grinds, as you can see in my photos, but it's not much. But the base, being hollow allows them to fall through to the counter top so they won't collect in blind hole. The hollow design of the base also allows it to be easily cleaned too. The needles are nice and long, and effective, but I foolishly bent a few on accident and I ruined the charm of how they looked when they were all perfectly parallel to each other.
I'm on the fence as to if this really makes a better espresso. It does eliminate lumps and evens out the grinds as it's designed to do. I usually use 14.0 grams of grinds in my portafilter, but to prevent a mess with stirring the grinds with this tool, I went with 11.1 grams, which was not enough to build up any pressure in my espresso machine. I realize with more use, I will get better and more comfortable with increasing the amount of grinds. I also just noticed that I could really benefit from using a dosing funnel while using this needle distribution tool, and would eliminate most of the mess. Coffee is always a fun adventure, and with this tool set, I've opened a new door to explore, but I think I really need a dosing funnel to do this one better.
I love the way this looks, and it really fits in with almost any setup with it's design, shape, and colors. This would be an excellent gift for any espresso lover out there, even someone who may not be so fanatical with the process. If you are thinking about gifting this to someone special, and you also happen to know what size their portafilter is (the diameter), then I strongly suggest getting a dosing funnel too so their first use is far more successful and pleasant than what mine was. The better their first impression may be, the more likely they will fall in love with this and want to keep exploring the possibilities.

Beautiful and functional
This is the first espresso distribution tool I've ever used, so I wasn't sure if it would really make a difference. I haven't had a home espresso machine for 15+ years, so I figured now that I am home more, I'd get all the accessories to do it right.
This is a beautiful piece that is very functional. It's simple to use to even out the grounds to provide for a more even flow of water through the coffee. Since I got this and used it from my very first espresso, I actually didn't test doing it without this tool to see if it made a noticeable difference.
Because I've never used one before, I'm not sure what features to compare to others, so I don't know if the current $24.99 is good or not. It seems high for such a simple product, and I probably would never consider getting it if I hadn't been given the opportunity to get one through the Amazon Vine program. But as part of my new espresso routine, I do think it contributes to making a delicious cup of coffee. It certainly can't hurt and is part of my regular ritual now.
