The glass can break if not careful. Also, sometimes if the hot water is poured in too fast you can end up with a few grounds in your cup.
This product is great because it's simple and this is the original. French press is all about exposing the true taste of coffee and I feel as though the Bodum Chambord gets the job done effectively. Before this, I used a French Press mug and I like the idea of FP on the run, but it's not realistic. Now I'll just French Press in the Bodum and pour it into a regular travel mug; it makes more sense to do it that way because when I would use the mug, the grounds would stay at the bottom the whole time and muddy the flavor of the bean.
