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

Would recommend.
Size: 58mm
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.

Great little temper
Size: 53mm, Color: Silver
Works great! Only problem is that it doesn’t have that feel of tamping. Wish I had more feedback. It just goes down very easily and doesn’t have that feeling of solid tamping. Now that doesn’t mean it’s not doing its job. Works fine but would like some manual feedback.
