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!

It is heavy
Size: 58.3mm, Color: Black
Item was as described and shipped promptly. It is heavy and works well with my portafilter. I haven't had it long enough to really evaluate how helpful it is.
