Good quality. Proper functional use.
Size: 58mm
It's all about the details. Functional and sleek design. I enjoy the satisfying click when applying the tamping process. The ease of use and not having to worry about uneven pressure being applied in the portafilter is why I purchased this. It gets the job done.

Great weight and super easy to use
Size: 53mm, Size: 53mm
I’m really happy with this tamper. It has a nice, heavy feel that makes it seem really well made, and the weight actually helps get an even press without much effort. It’s very smooth and easy to push, and it fits my 53.3mm basket perfectly. Definitely glad I bought it!
