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!

My tea stays warm to the bottom of the cup!!!
I am so glad I purchased this mug water. I drink tea all day but it cools down quickly. Since I purchased this mug warmer my tea stays hot to the bottom of the cup. The temperature is adjustable so you can keep your drink at your desired temperature. The top is glass and wipes clean easily. I like the rubber gasket that fits on top of the warmer. It keeps your mug in the center of the warmer and should you have a spill it catches the liquid. I've been using it every day for over a month now and it's going strong and is reliable. Perfect for personal use or as a gift.

Keeps my coffee as hot as I want it to be
Color: Silver
This coffee warmer is much better than the candle warmer that I was using for my coffee before. With a range of 3 temperatures, I have a choice of temperatures from hot to very, very hot, and the warmer shuts itself off after a while, just in case I forget. The description advises that ceramic cups do not retain heat as well as flat-bottomed cups, but I have not found that to be a problem. Coffee in my ceramic mug stays as hot as I want it to be. The knob on the side makes this warmer easy to turn on and to select a temperature, plus I feel that it is a good value.
