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.

Good but pricey.
The product is great and not only does it improve the flavour of the coffee but also prevents leaking / dripping during the preparation phase. It is expensive though for something so basic, I have three AeroPress devices, home, work and travel and if I were to want one of these for each it soon adds up.

The simple way to make great coffee just got better
Hands up, I've been a fan of the AeroPress for the last decade. IMHO its always been one of the best ways to cheaply make great tasting coffee without too much faff! I'm not the biggest fan of the "Pod" machines, they make good (not great) coffee but compared to using ground coffee which tastes better, the price per cup is high. Yeah of course I could always get a big coffee machine, but emphasis on the big (and expensive). So depending on my mood, for the last decade its been my Mokka pot or the AeroPress. So what does the Flow Control Filter Cap being to the party? Well, if you use the AeroPress in the prescribed manner, it stops the coffee dripping through while you wait, and when you do press you can force your coffee though at higher pressure. This makes for a strong coffee, without it being too bitter/acidic. This is where I have to hold my hands up for the second time. The current batch of beans I'm running through are medium roasted, so I still have to see how this addition works with darker roasts, and can it infact produce any crema. So my journey isn't over it's just beginning, but it's a great beginning!

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.

it's good but can leak
I've seen others have this problem and it appears I have it too. Overall I don't regret my purchase as I feel that it has improved the coffee but it does have a tendency to leak a little when pushing the coffee. Also the paper filter sticks to the inside every single time which is annoying.

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.

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.

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.

Fijne upgrade voor de aeropress
Aanbevolen door mijn favoriete Barista en inderdaad, wat een genot om deze toevoeging te gebruiken met de aeropress. Geen vroegtijdig doorlopen meer, weinig inspanning nodig bij het indrukken van de zuiger en geen nadruppelen nadat je koffie klaar is. Het enige nadeel is het pruttelende geluid wanneer het water op is en je de lucht door het membraan drukt. Dit kan ook voor enkele spetters zorgen maar deze blijven gelukkig wel tussen de mok en randen van de aeropress.

iş görür
Düz yöntem ile demleme yaparken bardağa boşa akan sudan bu kapak ile kurtulmuş oluyorsunuz. Demlemek daha pratik oluyor. Ters (invert) yöntemide kullanımı fark ettirmiyor, kullanabilirsiniz. Bu kapak ile kahve kreması çıkaracağını sanmayın, bir kapak ile olsaydı koca koca bilmem kaç barlı espresso makineleri olmazdı :)
