Espresso Tamper 58.35mm-3 Spring Loaded Coffee Tamper-15lb / 30lbs Replacement Springs Calibrated Tamper with Sound Feedback-MHW-3BOMBER Flat Base Tamper-Fits for 58mm Portafilter Basket T6184T-OS

The tamper looks and feels amazing. It has that satisfying click when pressed. Great ergonomics and built quality too. I am not sure whether it is ripple base or the spring, that makes a click, but something disturbing the puck in a way that causes more frequent channeling. I ended up switching to a spring loaded tamper with flat base and no clicks(had better results with such tamper). I am still not sure if it was me doing something wrong, or the tamper, so I still give it 5 stars.

This has been a great Tamper. It works perfectly with the breville 54mm portafilter. You get a very satisfying click at 35lbs. I highly recommend the product.

Phenomenal performance after two years of dialysis use and dropping. It matches my other tools and looks great on the counter. Does hold up over time! It is heavy and perfect size for my high quality espresso setup.

This is a well engineered percussive tamper that uses top quality precision manufactured components. It has a measured consistent tamp pressure of about 29.5 lbs. It has a dampening mechanism that minimizes the main-spring reset percussion so that it only feels like a mild tap and cannot possibly destabilize the coffee puck. It is a significantly better tamper than the violently percussive XAQMHSW Triple-Spring Impact Coffee Tamper (see Percussive Tamper Details).The tamper has a firmly seated base-plate shaft that doesn't wobble and a very smooth gliding action when compressing down on the handle. The stated 58.35mm rippled base-plate diameter is accurate (measured with digital calipers). The base-plate thickness is not sated in the Product Description but I measure it as 6mm from the top of the base-plate to the tip of the rippled peaks on its bottom. Fortunately the thin 6mm base-plate does not effect the calibrated tamping pressure when used on espresso machines like the Gaggia Classic that require a minimum 9mm tamp-depth (see Triple-Spring "Percussive" Tamper Details).It also includes an extra 15lbs main-spring in case you decide to lower the default 30lbs tamping pressure (20lbs main-spring can be ordered separately).Cons:1) The small bulbous handle is not very ergonomic for applying 30lbs of force which is probably why they needed to add the flange so that you could also use your fingers when pushing down. A larger 54mm diameter flat handle that had a very slight convex dome-top would have been much better and would allow using an opened-hand palm to apply the pressure.2) The base-plate thickness is only 6mm which results in a minimum 6mm tamp-depth at the puck's rippled valleys (the puck rippled peaks are at a slightly less tamp-depth). I use a Gaggia Classic espresso machine which, along with standard home machines that have a commercial-grade 58mm E61 compatible grouphead, has a minimum 9mm coffee puck tamp-depth clearance requirement (measured from rim of filter-basket to top of compressed puck). Most high-end 58mm professional tampers have a 9mm base-plate thickness that better accommodates this puck clearance requirement and avoids mangling the compressed coffee puck against the grouphead water-screen. With this tamper you need to always accurately weigh your filter-basket dose to make sure it compresses to a depth greater than the minimum 9mm clearance limit. A 9mm thick base-plate would have alerted the user of an overfilled filter-basket because the tamper leveling-plate would not be in contact with the filter-basket rim if the puck tamp-depth is less than 9mm when the tamper bottoms-out at 30lbs.A 9mm thick base-plate would also have given the tamper significantly more weight and lowered its center of mass. This combination would allow the tamper to function as a make-shift coffee puck leveler by simply spinning it in the loaded filter-basket prior to tamping.FYI - Triple-Spring "Percussive" Tamper Details:Single-spring and double-spring leveling tampers produce lower tamp pressure as the coffee puck tamp-depth increases. Only triple-spring leveling tampers can produce their calibrated maximum pressure independent of the puck tamp-depth. They have an internal release mechanism that stops the main-spring from compressing any further once the maximum calibrated pressure is reached, regardless of the tamp-depth. Triple-spring leveling tampers are also sometimes called "percussive" tampers when their pressure control mechanism stops the increasing main-spring compression force by suddenly releasing the compressed spring. This sudden percussive snapping-back of the internal main-spring, resetting it back to its initial compressed state before the tamp began, is what causes the tamper's "click" sound and the "tap" sensation. Excessively violent main-spring reset percussion can potentially cause structural cracks to form internally in the compressed coffee puck. Well engineered percussive tampers have an internal dampening mechanism that prevents excessively violent percussive resets.

This Tamper works amazingly well. The spring action gets it right each press. I love the look as well, it goes great with the other coffee gear on my counter. Its a little pricey for a tamper but it was well worth it to add to my setup

This is as great addition to my espresso bar making sure I have a nice even tamp. The craftsmanship is exceptional and it is heavy and perfectly machined. I measured the spring release at 33lbs but with a bathroom scale. Really nice!
