This is used nearly daily, it’s been about a month, and I haven’t noticed the needles falling out. I didn’t research if these needles were the right size for perfectly distributed coffee, but it breaks up my clumps very easily and efficiently. I made a lot of changes for my new espresso machine that have improved my coffee, and I would guess this would definitely be one of them. If you buy a WDT tool, I did my research and I can’t complain about this one that I bought. It even came with replacement needles. Would buy again. It feels nice, and I even wipe the needles after each use with a wet and then dry towel, and they still stay in place. You can bend them if you want them angled or straight.

Wish I had one before

Color: Matte Black

Nice little tool. I never used one before and it does make a difference when evenly distributing the grounds and taking any clumps out. Would recommend.

Nice weight, feels very high quality

Color: Matte Black

I did not expect the stand and handle to have such a nice weight to them, the stand does not tip or move it all when I am getting the distributor in and out. The tool itself also works great, and it even comes with extra needles if you need to replace them. Truly feels like a much higher quality item than the price would have you think.
