I would have loved to recommend the Bobble Presse.
It requires medium-coarse ground coffee. That’s ridiculous. Other coffee makers aren’t as stringent. For instance, the AeroPress works fine with an off-the-shelf filter grind.
Add the rubber lid’s repulsive taste and you have ample reason to steer clear of the Bobble Presse.
If you’re looking for an awesome low-tech coffee maker, read my review of the AeroPress. Spend your cash there.
