While the dimensions are fine, this tamper does not give a compact, tight press. I feel the cheap plastic tamper allowed me to put higher pressures on the espresso grounds and get a tight puck of grounds, as opposed to this steel tamper. Theoretically, better than a plastic one. Hope it works better for you all!
Only One Word for this product is 'PERFECT' it is about 600 Grams in weight and while using it one does not require any manually applied pressure to even the grounded coffee powder filled in the portafilter, it does its job perfectly.
