solid precision built. weight shy of 17oz (478g), aesthetically pleasing. the plunge operation quite smooth. took one star off per its one spring design, you tamp with whatever weight you put on it.

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!

Excellent tamp!
Size: 53mm, Size: 53mm
Love the tamp! The original one my machine came with was not great and I needed to buy one. I’m glad I picked this item, creates the perfect tamp and my expresso has been flowing much smoothly ever since

Very well made. Works like a charm. I like palm tampers and this one makes it a lot easier to get a level tamp!
