Excellent Product
Size: 64 Ounces, Color: Gray
Absolutely love this item! It was securely packaged and arrived beautifully. It is super easy to use, very sturdy, has no issues leaking, a slim and sleek shape that fits perfectly in my fridge shelf, the solid glass jar and thick, durable plastic makes this item absolutely perfect.

Great cold brew at home save yourself some money get it now
Size: 64 Ounces, Color: 2Pack-Gray
This is a great way to make cold brew at home. I love the look, and size fits in the fridge perfectly. The system could not be any easier to use put coffee in, and put it in the fridge. The glass seems to be normal mason jar thickness and the handle is nice and sturdy. Very nicely made for the price.

Great low profile pitcher

Cheap filter and non-ergonomic handle make this mediocre
Number of Items: 1, Number of Items: 1
I think this will get the job done, but the plastic and filter portion of the filter in the middle is really cheap plastic and I can't imagine it holding up very long.
I have a different pitcher with a stainless steel filter and it fits nicely, but this one just loosely floats around in the pitcher without being fixed and feels like it wasn't really designed to fit with the pitcher.
There is a warning on the box to not use hot liquids which makes me a little concerned about chemicals that may come off into the drink. It is advertised as a cold brew pitcher, so that may not be a concerned, but if you want some hot tea or something and then want to store it in the fridge with the pitcher, you would want to wait for it to cool.
The compact size fits well in the fridge, but the handle is awkwardly close to the pitcher body so that if I hold it normally, my knuckles are making contact with it, so it is not comfortable to pour.
The lid seems like it would pop off, but, despite being pretty rectangular, it twists off. It seems to hold pretty snugly, but after rinsing it out and starting some cold brew hibiscus tea, I didn't want to try holding it upside down to see how well it holds water.
The lid has a little locking mechanism to prevent it from opening that you slide. When it's unlocked and you press down to open it, it stays up until you manually push it back down, so you could consider that either helpful or annoying, depending on your preference.
Because the filter inside is so flimsy and doesn't lock in to the pitcher or the lid and the plastic not spring hot liquids, I can't say I recommend this. I think you are better off finding one made with tempered glass and stainless steel.
If you don't really care about the filter and just want a plastic pitcher because you have children or are otherwise concerned with a glass one breaking, I think this one could work well for you.

Not Quite As User Friendly As I Hoped, But Does Have A Good, Reliable Seal And Deep Infuser Basket
Number of Items: 1, Number of Items: 1
I really wanted to like this, but it wasn't quite what I had in mind. Perhaps if I was a regular cold brew brewer this would come together better for me. But I got it because I like infused tea and the center strainer in my previous pitcher broke/ wore out. I do drink cold brew coffee occasionally too, since it is easier on my stomach. But I had been buying it prepackaged from the grocery store. So when I came across this, I thought it was a great way to cover 2 things at once.
I did find some pros and cons. First, I like the size, it fits in my fridge door well. And the square shape conforms without taking up extra space better than my round pitcher does. I like that it can be put on its side, but I haven't been brave enough to do that yet. And I like that the infuser basket comes down far into the container.
Some of the things that were drawbacks for my use are the basket is rather large and takes up a good bit of container space. Granted, it is mesh and water can pass right through it as intended. And smaller would be harder to clean. Maybe it is a mental thing, feeling like it is blocking space, I don't know. Plus it arrived warped already, which makes me question how well it will hold up long term. And I sometimes like putting hot tea into my pitcher and this is labeled no hot water. But then it says it is dishwasher safe (top rack) which gets pretty hot, so I am afraid to actually put it in my dishwasher. And I'm not a fan of handwashing.
I like that it came with extra gaskets and seals, but who really keeps up with those things? I put them in my kitchen drawer, the one with all the weird extra things you forget about in it. And I'm sure I'll not know what they go to when the time comes I need them.
I haven't made cold brew in it just yet, sticking with fruit tea so far. I realized cold brew requires its own grind and a LOT of it. So it does OK for my use, but not a total homerun. It isn't totally user friendly, especially the lid. But glad to brew up some refreshing cold drinks for summer.
