Great product, thoughtful design, great customer service
Color: Black, Size: 40 oz
I don't write a lot of reviews, but I felt like this product deserved one. This is an excellent cold brew maker. It is very easy to use and has a great 1,200 mL capacity. The plastic construction is more versatile (less fragile) than other brewers made from glass. The filtration system eliminates the sludge that other brew systems leave. The packaging is very thoughtful - a scoop and sponge are included. The scoop is easily overlooked, but it is the perfect size to clean the used grounds out of the filter. The sponge is an unexpectedly useful form factor to help with cleaning. Hopefully the sponges can be ordered separately, since sponges don't last forever.
Some minor downsides:
Cleaning is moderately easy, but the only component that is recommended for the dishwasher is the pitcher (which is also easiest to clean by hand). All of the other elements are recommended for hand washing, which doesn't take long.
The way the filter is configured, the pitcher will work most effectively if stored (at least for part of the brew cycle) on its side. However, there is a vent in the lid that is prone to leaking when the pitcher is stored on its side. Brewing upright can lead to the top grounds not getting exposed to water.
Unfortunately, one of the pieces broke during routine use after a couple of months: the pitcher lid is attached with a couple of hinges that snap the lid into place on the pitcher. One of the hinge attachments broke. I contacted customer service and a replacement pitcher arrived four days later. I'd recommend being careful with these hinge attachments as they seem prone to break. At the same time, the customer service is very responsive and suggests that they take support of their products seriously.

Nice little cold brew pitcher
Color: Black, Size: 40 oz
Easy to use and very easy to clean. We have made one batch of cold brew so far and are very pleased with the results, the suggested measurements produced a very smooth tasting coffee. Definitely worth trying for the price.
