Stops retention
We use our Baratza Encore ESP as a single shot grinder. We weigh our 14g of beans in each time. We noticed clumps would sometimes come out at the end. I purchased the bellows and was amazed, at the end of grinding we can get between 0.5-1g of coffee out by using the bellows. So hopefully no stale grinds sitting in the grinder. Did look at a single dose hopper but this option looks and works great. Ps doesn't fit well upside down!

Misshapen out of the box
When buying a product like this, you'd expect it to be fairly uniform upon opening the box. Not so--the bellows I received are very clearly not that round and a bit flat on one side. What this means is that they don't compress evenly and a gap forms on that flat spot. It's not good. I'm hoping another one can be sent out as a replacement.

Poor quality and over priced
I'm not sure if I've been sent a returned item or if this is a common issue (see video) but either way its a product I would avoid. The bellow doesn't compress in a uniform manner as can be seen in the video, very similar to another review on here. (The box looked like it had been opened so it may have been a returned product.) The faulty compression folding causes a kink on the rim of the bellow where it sits on the hopper causing air to escapes from the top instead of pushing it through the grinder. It does push most of the air through though and does seem to push out the grinds, its just very inefficient. The kinks and the manner in which it collapses doesn't fill me with confidence and I imagine the rubber will crack at these stress points in the not so distant future.

Bad fit
I'm surprised this has such high reviews, this is quite a disappointing product for the cost. Firstly, the bellows don't really fit well on the Encore ESP. If you're not careful it will fall off along with the lid. Secondly, it doesn't really work well for single dosing because it requires you to use the stock hopper which is large and prone to collecting residual coffee. If you're looking to single dose, this isn't it. Get bellows that work with small hopper. On the plus side, it does seem to do quite a good job at getting coffee out of the burrs with just one press.

Funciona a la perfección. En mi caso tengo una Baratza encore esp y me ha ayudado a sacar toda la molienda y se no queden residuos dentro del molino.

Does exactly what it should do, and it’s affordable. It does however add 2 1/2 inches to the height of the grinder, which may be a problem for some .

Stays on the hopper but the hole lid doesn’t stay on top, it’s too big. Needs to be a firmer material/silicon.

I bought this for my Baratza Encore ESP. It fits perfectly and works exactly as described. Very happy with the purchase.

I bought this bellows to reduce retention in my Baratza grinder, and it works exceptionally well. It fits perfectly on the coffee bean hopper, and the lid also fits without any issues. The material feels durable and well-made, so I expect it to last a long time. I consider this an excellent accessory for the Baratza Encore ESP. When grinding for espresso, retention can reach around 0.5 grams, but with this bellows, and using the RDT technique, it’s reduced almost completely. If you want more consistency and less coffee waste, this is a great addition to your setup.
