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.

Wonderful grinder:
Color: Silver
This is one little powerful grinder. It holds 30 grams in the glass jar which is perfect for 2 cup 10oz cups. It has a dial to adjust the grind. Great for two! It works great. Really good purchase. It is a labor of love.

Wow, very well constructed, grinds all sorts of things perfectly. Completely happy. Looks great, super easy to use, nice size, little glass jar, very quiet, love that it's true ceramic. Handle comes off easily to store. Nice! :)

Great coffee grinder!
Color: Silver
Amazing product. Easy to use and has different grades of grinding. Zero noise compared with an electric grinder and more control of the results (consistent). His size and weight make it portable and easy to carry.
