Great cold brew maker!
So far this has been a big improvement from a different brand cold brew maker I had. It is simple and easy to used doesn’t leak. The coffee comes out tasting great! It has a smart design that works well. It’s a great deal for how well it works. It is big enough to last all week but not take up to much space in the fridge.

Air gets trapped in the filter so it won’t fully steep
Color: Black, Size: 40 oz
Filter doesn’t let air out. It’s weird about all these positive reviews bc I tried cold brewing tea two times overnight but the filter holes are so small that basically it traps a large air bubble inside with the tea leaves. The water was barely steeped. It was weird enough to the point where I thought there must be a clear film on the filter that I hadn’t removed. When I loosen the lid all do the air rushes out and it fills w water, but when you tighten the lid any air inside with your grounds/leaves is trapped and prevents steeping. I kept thinking it was me based on all of these positive reviews but I could not prevent the massive about of air from getting trapped in the filter. If they made the holes bigger (not too big to let grounds out but currently you could mistake it for plastic film) then it would’ve been perfect. Nice size and about what I’d drink in a day or so. Change the filter hole size to let air flow out and I’ll buy it back!

Great value / great look
Color: Silver, Size: 11.8 Ounces
Very nice stainless steel frothing pitcher but the Latte art pen is very small, much smaller than I expected. The size is perfect for working with one Latte at a time. All in all a nice product. No real complaints...I mean, what can go wrong with a frothing pitcher :)
