I LOVE this!
Style: 1pcs 64oz green
I LOVE this! I've been spending too much $ for too many years on expensive cold brew coffee. Even from the grocery stores..with this I get really rich flavor and I completely control WHAT goes in my coffee. Glass is really decent quality. It's not flimsy. The plastic cover is just ok. I don't use a dishwasher, but I could see it not fairing well in a dishwasher. It works great for me and I'm saving sooo much $ now on coffee. Definitely recommend

Easy to use, but you got to find your right strength!
Style: 1pcs 64oz black
Fantastic cold brewer! My only issue is the bag of coffee for cold brew had one set of instructions (ratio of coffee to water) and the brewer had something different. So I brewed my first pitcher and now I know what I need to do to tweak it. Considering how much a cup of cold brew costs at a shop, I’m stoked to be able to make my own at home! And it was delish!!!! And you can brew it at room temp, but brewing it in the fridge will yield a smoother and less acidic taste, if you can wait that long for the result ;)

You can make great home brewed coffee
Style: 1pcs 64oz pink
It makes making your own cold brew very easy. It doesn't leak and cleaning is super easy. The jar is great quality. It's glass isn't thin or fragile and takes up about as much room as a half gallon of milk. If you want something that makes home brewed coffee easy I would get this. It does come with instructions.

Nice set
Style: 1pcs 64oz black
Very nice to get everything together. The jar is very thin, when I received mine the jar was busted, so I sent it back for a refund. Otherwise I thought it was a great buy.
