Worth it - just buy it!
Color: Matte Black
After a month experimenting with my new Breville Barista Express, I finally decided that a few of the basic accessories actually would make a difference in my coffee, so I got this as well as a distributor tool, and there is a noticeable difference. I consistently get excellent extractions, where before, I would occasionally get a shot that clearly was not distributed and tamped properly. The price for these tools was combined, less than $30 and most definitely worth it!

Great to use, little difficult to put away
Color: Matte Black
It's a perfect wdt tool and works wonderfully for it's entended purpose. Great weight to it and the base, however the base to store it is very slim, making it difficult to replace once done.

Good
Color: Matte Black
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.
