Solid build quality and surprising heft. Has a closer fit in the Breville portafilter than the Breville supplied tamper. This device is slightly different to a normal tamper in that it relies on getting the right quantity of coffee in the portafitler to get the right compression... once you get that right this tamps the coffee perfectly every time - it can be adjusted to the right depth and then locked in place too (you can check the depth setting against the depth recommended from the brevile razor tool). Really good device and a perfect add-on to the great range of Breville espresso machines - I have the Breville infuser for reference. This has totally replaced the use of the normal tamper for me and would really recommend providing that you have a consistent way of getting the same amount of coffee into the portafilter each time.
