Mostly great, except one little annoyance
Color: Black&Silver, Color: Black&Silver
Pros- lightweight, small, very accurate, easy to clean, timer included.
Cons- I use this to brew espresso on my Breville Touch and to get an accurate reading, you have to place something flat (structured) under the scale. Otherwise the reading just jumps all over the place. I know lot of espresso machines have the same base, so this might be an issue for some!
This is my reason for 4/5 stars. It’s an easy fix, it’s just kind of annoying. Value for the price seems to be on point. It’s easy to clean. It has a timer as well as scale (nice for espresso). Buttons work the first time you push them.
That’s it that’s all

A solid upgrade!
Size: 53mm, Size: 53mm
This coffee tamper has been such a nice upgrade to my espresso routine. It has a solid, balanced weight that makes tamping feel smooth and effortless, and the textured grip gives it a really comfortable, secure feel in hand. There’s something satisfying about how neatly it presses down the coffee grounds—like it was made to fit perfectly.
Since I started using it, my shots have been more consistent, with a beautiful crema and better flavor overall. If you’re looking for a tamper that’s simple, well-made, and does its job really well, this one’s definitely worth it.

It's pretty
Size: 51mm
I've never had a tamper, I don't know what I'm doing. But it seems to work just fine and I like the wood.

nice built, simple one-spring design.

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.
