Very useful, worth the spend
I think this is entirely fab. It solves the drip through problem so you now don't need to invert (which was always a silly idea), occasionally adds a nice bit of foam (with a paper filter), makes it a little easier to work with finer grinds, and gives you the flexibility and control to work through different recipes and refine your process. Personally I prefer using a paper filter on its own. It fits fine -- I think a lot of concern about leakage in use actually comes from the practicality of the deeper cap. It does seem expensive but to my mind it is paying off. After a few hundred coffees, here are things you need to know: If you are used to filling a mug to the brim with the standard cap, you will get a lot less in that same mug without leaking, because this cap sits deeper. Even if you give it just enough room, the spray from the nozzle will force some leaks through. You do need to keep the nozzle clean. The smallest amount of coffee solids will hold the nozzle open and you'll get a drip (or it might even squirt some coffee through if you knock it). So if you see a small indentation (or worse a tear) in your paper filter, that is a sign you need to clean the nozzle. It's easy to clean the nozzle: once you've rinsed off the cap and the lid, put the plunger back in, put some water in the Aeropress chamber, put the cap on, press the water through the nozzle, then pull the plunger back a little before removing the cap. That will push water through the nozzle and then pull it closed, and it'll work beautifully the next time. I do this about every three times I rinse, it's quick and easy.

An excellent addition to my Aeropress setup.
I have given it a 5 star because it does genuinely elevate the Aeropress product and it's great to get the crema. As many have noted, the price is a little crazy for what is essentially an engineered piece of plastic, but if you buy it and make multiple coffees a day it's well worthwhile I think.

Nice accessory, makes consistent coffee, but it's harder to use
I treated myself to this as a highly recommended accessory. Honestly, I do like the principle of it, I'm not sure it makes *better* coffee, but it's certainly more predictable strength and taste. Definitely not essential, but if you fancy trying a new gadget, go for it. Stainless steel filters work perfectly, but it is NOT compatible with paper filters -- they will be shredded by the "teeth" when you attach the cap. (Worth noting, I already bought a stainless filter years ago for the standard cap, but it dripped coffee everywhere, so I've been using paper filters, until I bought this new cap.) You do need good dexterity & finger grip strength to remove the cap afterwards, it's MUCH tighter & stiffer than the standard cap. Protip: pull the plunger back about an inch before you try to turn the cap as this takes pressure off the "teeth" inside. After I've turned the cap, I still need to firmly grip & wiggle it loose. Very easy to clean, just remove the cap, push out the coffee plug straight into the garden, and rinse, same as the normal one. I'd give it 5 stars for design, but deducted 1 for value for money, it's not cheap

This should come with the Aeropress
I'm so pleased I bought this. I no longer need to do the risky flippy method that's caused all sorts of messes and minor injuries to avoid the weak drips that happen with the normal Aeropress method. I also no longer need to even get a mug to start the brew, just pot it down on the counter and start making it, not a drop gets spilt. I use it for a full "4" almost-a-full-mug brew with 15-16g of light roast coffee, but have also used it to create a faux espresso as I assume was intended. I didn't get any crema at all, but the taste was good following a 20g coffee 50g water recipe with 30s agitated brewing followed by a fast press all the way through the grounds. Note: It makes some interesting "flatulent" noises both at the beginning of the brew and the end, as the valve pushes air through, but who doesn't like a fart noise? My wife's review is that it's better than the sound of my grinder anyway!

Who knew you could charge so much money for plastic?
Didn't really enjoy the price (it's a bit of plastic with a squeezy ketchup bottle valve in it) but I have to say, since buying it, I haven't stopped using it and it's so much nicer to make Aeropresses 'the right way up' as opposed to the often dangerous inverted method. Doesn't fit the Aeropress as well as the original cap though. You have to 'force' it on and screw it into place unlike the original. As you're probably aware, Aeropress is now owned by greedy venture capitalists that bought the good name of Aeropress from the creator, Mr Alan Adler. They've brought out a bunch of new Aeropresses and anciliiaries for the Aeropress, but by jingo, do they know how to charge for them! Between you and me, you can buy a no-name version of this for a fraction of the cost but I've no idea how well it'll work by comparison. Anyway. A begrudging 5 stars because it's great at what it does. All that cash for a few pennies worth of plastic does leave a metaphorical sour taste in your mouth though.

Expensive for what it is
It's good for using your Aeropress without drip-through during brewing, but after a few months the silicone pressure valve in the middle will lose its elasticity due to the oils in coffee and will no longer pop closed after you stop pressing. The valve is easily removable and should be replaceable but Aeropress don't sell them as spares, so you instead have to splash out another £30 on the whole cap, hence the rating. These types of food grade silicone valves typically sell for pennies in bulk from manufacturers, but finding the exact size and shape required by the flow-control cap is difficult.

Simple to use, improving the brew process and quality of coffee
I have used an Aeropress for the past year and have been really pleased with it. It has saved time and money queueing at Costa Coffee for a mid-morning caffeine fix, whilst allowing me to enjoy a superior coffee from my choice of freshly-ground coffee beans. My only problem was that when I added hot water to the grounds, a variable amount would go straight through to my cup before having a chance to brew. This flow control filter cap solved this problem by ensuring that the water stays put until the brewing process has been completed. I used the flow control filter cap with my standard paper filters. The quality of coffee is definitely improved by using this cap. It has a better crema and a smoother taste. The filter cap is easy to grip, making it simple to twist on and off. The filter paper sometimes stays in the flow control filter cap, something that didn’t happen as often with the standard cap. However, it is easy to remove the paper and rinse out the cap so it is ready for its next brew.

Best to make pseudo-crema!
Love this product! It fits nicely and seals completely so no drip flows through (unlike the standard aeropress cap). Intuitive to use as you just cap it on the press. Like the aeropress, it is very easy to clean. Just rinse it under water. It makes great pseudo-crèma on your espressos when matched with the paper filter - great alternative if you don’t have the funds or space for an espresso machine. You won’t get the crema if used with a metal filter. Word of caution if using with paper filter, don’t push too hard otherwise you’ll break through the paper and have coffee splash everywhere.

Buen producto, es distinto al método tradicional
Primera vez que lo uso, genera una taza más limpia y uds menos presión, requiere todo un mundo por recorrer

Worth the Money
Pricey, but it stops the pre-press drip, which I feel does improve the flavour of our coffee even more. It's well made, too, so I expect that it will last many years. Happy that I bought it.

Must have accessory
Great addition to my standard aeropress. Totally no drips, holds well and releases with steady pressure (albeit a tad squirty). Able to maintain a nice extraction all the way.

Sehr praktisch für tägliche Nutzung - empfehlenswert
Ich benutze den Flow Control Filter fast täglich mit meiner AeroPress und bin damit sehr zufrieden. Für mich macht er die Nutzung etwas einfacher und kontrollierter weil der Kaffee nicht direkt durchläuft. Dadurch fühlt sich die Zubereitung sauberer und sicherer an vor allem wenn man den Kaffee erst kurz ziehen lassen möchte. Die Kappe passt bei mir gut und macht bisher einen stabilen Eindruck. Ich hatte bis jetzt keine Probleme damit und finde sie im Alltag wirklich praktisch. Zur langfristigen Haltbarkeit und dazu ob oder wann das Ventil irgendwann ausgetauscht werden muss, kann ich noch nichts Sicheres sagen. Nach meiner bisherigen Nutzung funktioniert aber alles einwandfrei. Für mich ist es ein sehr nützliches Zubehörteil für die AeroPress.
