High quality french press
I really like this french press. It is made from high quality stainless steel and does not rust or show signs of degradation.
Easy to take apart and clean.
Everything fits and works properly, the filters work fine.
It stays hot for about 3 to 4 hours if filled to capacity.

FIRST use of ziruma french press
This is a great, clean French press with no plastic parts at all.
The filter mesh is excellent, and the brew comes out very clean with minimal sediment.
Quality: Good but not superb.
There is visible welding on the handle (see attached picture). I was expecting it to feel heavier overall — especially the lid, which weighs only about 180g (6.3 oz).
Thicker walls would make the pot heavier and give it a more premium feel.
The lid could really use a lock or twist mechanism to hold it securely in place. With this one, you have to hold the lid down when pouring out the last bits.
All in all, it’s a solid French press that works well for daily coffee use.

Definitely worth the money, Great Product!
Looks great, well built, very solid! Easy to use. I’ve used the glass French press coffee makers in the past and decided to switch to this one. I’m glad I did, the coffee stays hot and there is very, very, very little sludge at the end!! I just wish that I didn’t wait as long as I did to make the purchase! Definitely worth the money! Great buy!

AWESOME!
This is my first time using a French Press for coffee, and I chose Ziruma for its looks and durability.
It's beautiful and works even better. No coffee grinds, just smooth, robust coffee that stays hot due to its double-walled design.
