After buying 2 other tamps that measured 58mm instead of the advertised 57

5 i spent more money on this 57mm and thankfully its actually 57mmvery well made the extra weight makes leveling the grounds before applying pressure much easier using on a francis francis x3 with nonpressurized portafilters it is easyish to pull perfect shotsa welcome surprise is that the stainless handle is not one piece but threaded and removable so getting different bases is possible
