MHW-3BOMBER 51-54mm Espresso Coffee Powder Receiver Container Espresso Grounds Cup 51mm/53mm/54mm，Black DR5504B

It works as promised! I do get some grounds sticking to the insides that do not shake out. I do not currently use RDT on my beans, so that could fix this, but I don’t like the idea of moisture in my grinders. Overall it’s not a big deal and it’s not a huge amount of grounds. Espresso from my Flair 58+ is still top tier. Currently using a Izpresso JX Pro grinder

I love this shaker but you really need to use a portafilter funnel. It fits a 51mm to 54mm portafilter but it's not easy to use in that configuration because the portafilter will be overfilled (depending on the amount of coffee you use, of course). I use 16 - 18 grams of beans and in a 51mm portafilter, the grounds are so fluffy the portafilter is overfilled and when you remove the shaker, the grounds go everywhere! Just place your portafilter funnel as you normally would and then empty the shaker over the funnel. It's amazing how fluffy and clump free the coffee grounds are. I then WDT just to evenly distribute the top, then (very important) a couple of light taps of the portafilter on your tamping mat, then remove the funnel and give it a good tamp and I have my "elixir fix" in no time. One thing...you'll produce a little static during your shake. If you remove the lid, you'll see quite a lot stuck to the inside of it. Before you open it, hold the sides of the shaker and keep your finger on the lid, then smack the shaker lightly (down) onto your knockbox or tamping mat or whatever. This will dislodge the grounds from the inside bottom of the lid (most of them) and you're all set to empty the contents into your portafilter. Nice invention and according to science, you'll get better extraction than just using WDT...or any other distribution device.

Completely eliminates the need to wet your coffee, which totally changes up the game, but it does take longer (albeit a negligible amount) compared to just stirring with the wdt. However, I’ve never had a bad shot with squirting with the shaker vs using wdt. I’ve had it for quite a while and the finish did come off a little, but still does the job and I have no intention of throwing it away yet. One thing I will have to say is the leftover coffee dust that sticks onto the shaker does trail no matter how hard I shake it off. With this mind I have to remember to brush it off after each use, which makes me wonder if I should just wdt instead. Either way, it’s a great tool and is an amazing alternative to stirring your grounds with wires.

This is a very nice shaker, one of the best I've seen. It's too bad that the one I received is used. It has dry fine coffee grounds on the inside of the shaker. Very disappointing and not even really sure what to leave as a rating.

The MHW-3BOMBER 51–54mm espresso coffee powder accessory is a solid upgrade for my espresso routine. It fits securely on my portafilter and helps keep grounds contained while dosing and distributing, which means way less mess on the counter. The build quality feels premium and sturdy, and it sits flat without wobbling. It makes prep faster and more consistent, especially when using a WDT tool or leveling grounds before tamping. If you use a 51mm or 54mm setup and want cleaner workflow with better control, this is a great buy and absolutely worth it.

Well made, but a waste of money. Shaking the grinds before puck prep is overrated.

After hearing about a $100+ tool like this and what it can do to level your espresso game up, had to try it and there’s no going back! My only complaint is how much static and grinds do stick but could just be the dry climate I’m in. Over all. Get this and not a wdt tool, plus c, plus d. You just need this and a nice tamper!

Beautifully made, very high quality. Parts fit together perfectly. Fits my 58mm portafilter exactly and drops the coffee without spilling the powder everywhere, so saves making a mess. Works well and I found it reduces static in the coffee powder.
