AIEVESilicone Bellow Compatible for Breville Barista Express, Single Dose Hopper for Breville Espresso Machine,Gray

Fits perfectly on the Breville Dose Control Pro so we can use one grinder for both decaf and regular beans.It's such a simple concept but it works perfectly.As you pump down on it, you can see the grounds pulse out of the chute. As the hopper empties, you can easily tell when there are no more beans in the hopper because the sound of the grind becomes a high pitched whir.This bellow doesn't do that great a job at pushing the whole beans into the grind mechanism - - - I find that I still have to either give the machine a few bumps or just use my hand to loosen the beans stuck to the sides - - - but it does do a great job at flushing all the grinds out of the machine so there's no residual left in the chute.* * * Just a tip that has nothing to do with using this bellow:- - to greatly reduce and almost completely eliminate the static mess of grounds, sprinkle some water on top of the beans in the hopper before grinding.I fill the hopper about halfway, run my hand under the tap and use my wet hand to mix through the beans. Fill more beans to the top, wet my hand again, then mix through the top half.Seriously - - - almost no flyaway grounds at all.

Item works great.Whatever weight beans you put in you get out.Item was bought and fits the Philips barista brew. Philips barista brew lid does not seal against the hopper fully but sits atop and is the same diameter.It still does its job with no issues.Highly recommend.Very easy to install, durable, easy to clean, and the grey color looks good with the stainless steel.

Simple, inexpensive, and effective. The Breville Smart Grinder Pro typically retains a fair amount of coffee - I used to smack the top of the hopper every time I used it to try to get all the coffee out. With these bellows it’s quiet, quick, and easy to get virtually zero retention. Wish I knew about this years ago.

I measure my coffee beans for making espresso so I have been searching for a single dose hopper attachment. However, I could not justify paying extra $50 to$100 dollars just to replace the hopper so that I could save few grams of coffee grind. When I saw this AIEVE hopper attachment, I was little hesitant but I had to give it a try.Silicone pretty thick and material does not feel cheap. Install was super easy since all you have to do is put it between the hopper and the lid. I purchased the grey option and was surprised by how similar the color was to the Breville's stock lid. It looks good with my Breville Barista Pro as pictured, almost looks like it came with the machine.I measured 18grams of coffee beans and using the new hopper attachment I got the full 18grams of grind just by pressing the lid 3 to 4 times at the end of grind. Super excited that it worked! No more tapping the machine or trying to create pressure with the lid to get the full grind.The pressure that this attachment creates is not strong enough to "clean" the hopper/grinder from all of its tiny bits of grinds stuck to the wall, so don't expect your grinder to be cleaned using this attachment.I am taking off one star due to the fact that the silicone stays attached to the lid instead of the hopper as pictured. I was hoping that it would be secure to the hopper and that I could just open the lid, but it's not too bad once you get used to it. I guess you can purchase this attachment for the purpose of storing more coffee beans in the hopper, but I don't really recommend it due to the fact that it secures to the lid instead of the hopper.For those like me who wanted a single hoper but could not justify spending lots of money for other single hopper options, I highly recommend this attachment!

THE SHORT: If you weigh your beans, this device turns your Breville grinder into a zero-retention grinder, allowing you to be more consistent with your espresso.THE LONG: For the past month, I have weighed before and after grinding my beans. I've found that the Breville grinder is on average a zero-retention grinder +/- .4 grams approximately. What that means is sometimes you'll get all your beans through the grinder, but you might get, .3 grams less the next time, and then .1 more the next. This obviously throws off your brew ratio slightly each time, but it also means sometimes you're getting yesterday's ground beans. It's a very small amount, for me, this device was worth it.It allows you to remove yet another variable, making your espresso more consistent, giving you a stable data point to adjust from. And again, a few tenths of a gram doesn't sound like much, but I've found that a brew ratio even slightly higher or lower than 1:2 can yield noticeably bitter or sour coffee respectively.The bellows are high quality and we've already established that they work well. I had a complaint that they held onto the lid better than the grind funnel, but then I realized that this wasn't really an issue if I just treated the bellows as part of the lid and stopped trying to fight friction. lol. Also, this system is rather large, it just barely clears the underside of my cabinets, but it is significantly cheaper than smaller options and that's worth it to me.

This is a great idea. It just slips on and more than doubles the capacity so I don't need to refill the hopper as often. I don't use the bellows much, but it works good, too.

Works great, fits my breville machine perfectly

This handy gadget works as advertised, up to a point. It IS great wringing the last grounds into the portafilter but is NOT a substitute for removing the hopper and further removing the few unground beans and cleaning the burrs before changing to a different bean.In everyday use with the same bean I would definitely recommend this purchase. Not so much if you change varieties of coffee beans throughout the day or during the week.
