At first I did not think I needed this, but after using it for almost a year, I have found out how amazing this product is. It makes the coffee I get much better and lets me pack the grind much more evenly. It is also made of entirely metal, which adds a lot of weight and makes it feel super premium. After using it almost every day for a year now, I still have not needed to replace the needles, yet it came with nine more. All of that value for such a small price makes this great for me and anyone looking to improve their coffee making.

Great little tool

I recently purchased this product after upgrading my grinder. So far it had worked well and the little magnetic holder attaches perfectly to the Breville Barista Express I have. I love that it’s magnetic and keeps the tool out of the way and in a secure spot. Additionally, they throw in a double sided 3M sticky pad for those who do not have a surface where it can magnetize to. Overall great WDT with a great storage solution.
