Single Dose Hopper Compatible with Eureka Atom Espresso Grinder Aluminum Single Dose Coffee Grinder Hopper and Lid with Silicone Bellow Air Blower

Took me a while to find a single dose hopper with bellows for my grinder and this one fits perfectly on the Atom Eureka Specialty 75 with its 53 mm diameter inlet. Beautifully made and looks more expensive than it is. You have a choice of two very well-made bellows seals: a flat metal piece and a clear, convex plactic seal that fits the palm nicely. Both seal the bellows very tightly at the top. This was a big bonus. It blows all residual ground coffee from the chamber and shute. Very happy with my purchase. Amazon's international shipping was ridiculously fast, as always.

Well made, heavy duty single dose attachment that I'm using on my Shardar grinder. It fits perfectly and works like a charm. Highly recommended.

I got this for my Eureka Atom Specialty 75. When I ordered the grinder, it came with a massive hopper and I was primarily looking to single dose. After searching around on the internet, I noticed a lot of single dose adapters were 3D printed. I debated 3D printing one, but then I saw this and that it was made out of aluminum. The adapter fit snugly and has worked beautifully over the past week. You'll notice in the picture that there's a small gap in between the grinder and adapter. It might be possible to push it all the way down, but I didn't want to force things... and the gap doesn't bother me given the fact that it fits so well. I've mainly used the aluminum cap on it, so I can't comment on the plastic one that it also came with. The seal is good and allows the bellows to blow air through easily. If you watch the video you can see the amount of coffee it blows out on the first go. It has truly made my grinder zero retention. I always get out what I put in to within 0.1g (keep in mind that your grinder AND the bellows will determine this bellows don't always = zero retention). The small plastic bonus bean cup they gave is pretty nice. I use it to weigh out and dose beans into the hopper. However, the spout at times seems a bit too small to allow beans to easily go though. I mainly just the scoop side. Either way, I wasn't looking for this -so it's a nice bonus!

As a passionate home barista and Rocket R58 owner, I’m constantly fine-tuning my setup to achieve the best possible espresso. At first, I wasn’t sure if this product would fit my Rocket Fausto grinder, but ChatGPT suggested it would—and indeed, it did. The product exceeded expectations: it’s solid, heavy, and very well built. It adapted seamlessly to my Rocket Fausto, turning it into a true single-dose grinder. This not only improves workflow but also ensures fresher and more consistent extractions on my Rocket R58. If you love specialty coffee and want more control over your grinder, this accessory is a game-changer. I fully recommend it.

Aluminum Single Dose Coffee Grinder Hopper and Lid with Silicone Bellow Air Blower. It works as advertised. Other than price, it just works as expected. BTW, this fits the Shardor 64mm flat burr grinder perfectly. Would recommend

High quality. Great price!

The coffee scoop is missing. I was counting on it to measure and load the hopper. For the price I paid I should not have to make another purchase for way to measure and load coffee into the hopper.

So far so good. If you want to single dose an Atom series grinder this product works great! It looks great too!
