Query: Elegant Design, Smooth Coffee...but FRAGILE!

Similar in design to the classic Chem-ex coffee maker, the Bistro by Bodum makes smooth, delicious coffee. The insulation works well and the rubber gripping ensures ease of use.I adored this coffee maker, but give it just 4 stars because a very slight bump while washing it caused the glass to crack.
