Bests & Worsts Reviews from Amazon

This calibrated tamper works like a charm & has made a noticeable improvement in the consistency of my shots. The tamper is attractive, hefty, well-made & reasonably priced. It fits perfectly in my Gaggia Factory 106 manual lever espresso machine's 51mm single and double baskets. (The Gaggia Factory 106 was essentially a limited edition, rebadged version of the still-made and much more commonly found La Pavoni Millennium.) BTW, with respect to the pressure accuracy issue... I can't especially vouch of my decidedly non-laboratory test methodology. Such as it was, however,it consisted of using our bathroom digital scale (with, of course a clean folded-over paper towel between the tamper and scale for sanitary purposes! ;-) ). I then pressed the tamper down on the scale just to the tamper's fully depressed position and then held it there in place until the scale readout registered, without noticeably increasing the pressure beyond that needed just to hold the tamper in place in its fully depressed position. I repeated this three times and got readings of 27.9 lbs, 33.1 lbs & 29.6 lbs, respectively. To me, those readings seem reasonably close to 30 lbs...
