Makes excellent cold brew
Number of Items: 1
I thought I'd be using this in the summer, but a recent heat wave made me want to move away from hot coffee. I put in about a tablespoon of fresh-ground coffee per 8 ounces of water, and then another tablespoon on top of that. The coffee after around 12 hours was a medium-brown but intensely tasty; the next day it was darker and fuller but still very similarly tasty. I was very, very pleased. The mesh of the filter is extremely fine, though I went with a coarser grind so had no concerns about ground leaking through, which none did. The filter is really thin, though, so I need to be very careful when cleaning it out. That's the biggest flaw, actually, though it's not substantial enough to give it only four stars. It's just a bit tricky getting the grounds out any other way than just running water through it and rinsing it out. Otherwise, this lives up to the hopes I had for it. The spout has a very solid positive seal on it, so that's very reassuring. It doesn't take up too much room in the fridge, either, so I'm pleased about its form factor.

SlimFit 64oz Cold Brew Coffee Maker
Number of Items: 1
I bought this cold brew coffee maker mainly to stop buying iced coffee every day, and honestly it’s been a great little upgrade. The 64oz size is perfect for making a few days’ worth at once, and it fits nicely in the fridge door without taking up too much space. The filter does a good job keeping grounds out, and the coffee comes out smooth and not overly bitter. I also like the ergonomic handle — it feels sturdy and easy to pour even when the pitcher is full.
What stood out most is how versatile it is. I’ve used it not just for cold brew, but also for iced tea and fruit-infused water, and it works well for everything. The lid seals tightly so there are no leaks, and cleanup is pretty simple since the filter rinses out easily. The plastic feels durable and lightweight, which is great for everyday use. Overall, it’s a practical and affordable option if you want homemade cold drinks ready in your fridge without much effort.

Best cold brew system I have used. Produces consistently smooth coffee
Number of Items: 1
This iced coffee maker is a fantastic addition to a busy kitchen, especially if you value fridge space and a clean cup of joe. The slim design is a major win; it slides perfectly into the refrigerator door, leaving plenty of shelf space for everything else. Functionally, the filtration is top-notch. The internal membrane is fine enough that it blocks every bit of sediment, ensuring that the final cold brew is smooth and entirely grit-free. It’s a leakproof, reliable system that makes the brewing process remarkably simple.
I’ve been using this to keep a fresh batch of cold brew ready for my mornings, and the quality of the coffee is consistently excellent. It’s much more convenient than a standard French press for this specific task, as I can just set it and forget it overnight without worrying about spills or a messy cleanup. However, the initial setup was a bit of a puzzle due to the lackluster instructions. I spent a fair amount of time tugging at the top before I realized it’s a simple twist-off lid. Once you get past that "spoiler alert" moment, the operation is completely intuitive.
Aside from the initial learning curve with the lid, I haven’t run into any issues. It’s easy to clean, easy to pour, and does exactly what it’s supposed to do without any fuss. If you’re looking for a low-maintenance way to make café-quality iced coffee at home, this is a sturdy and practical choice. It’s a great value for anyone who wants a dependable brewer that stays out of the way until you need it.

Good cold brew maker with a few quirks
Number of Items: 1, Number of Items: 1
Overall, I really enjoyed this Slim cold brew coffee maker. The only complain I have about is if you try to pour it too quickly, the fluid will spill out of the tip. Also, I don’t like how the locking mechanism works for the lid. If you twist it on and you start in the wrong position the spout will end up backwards. The filter is nice and does not allow any coffee grounds to escape. I also like how it’s thin and can fit in the door of my fridge.

Minimal design, practical use
Number of Items: 1
This looks exactly like what is on the picture. It's not super thin plastic in that I accidentally have bumped it against both the fridge and my kitchen counter and I haven't seen any cracks - it's got some thickness/bounce to it. The seal is a twist on (which is not clear or on the instructions), which I think will help with any chance of leaking. The infuser goes the entire length of the container which is really nice because then things stay submerged, rather than some infusers where your fruit or tea only sits at the top of the container.
It's pretty sleek, but that does mean this is really tall. It's kind of tricky to fit in most fridges unless you put it in your door handle. I know the picture shows this being laid down on its side, but while I haven't noticed any leaks, I still wouldn't be comfortable storing it like that especially since the top is just kind of a button you click if you want to pour.
Overall, I think this is surprisingly solid. It has more functionality than a plain basic pitcher, the seal seems snug, and it has a relatively nice, minimalistic design. Only downsides are that you cannot use it for anything warm, and I expect the rubber seal is going to weaken over time as you twist it on and off. Additionally, you will need to clean this, so it remains to be seen if it picks up any residual smells/tastes as most plastic is going to do.
