Outstanding Reviews

We launched Rumble Jar on Kickstarter in late 2017 and have been blown away by the reception ever since. Heck, it even earned us a Kickstarter Project of the Year award! Just have a look at our reviews.

You can count on the high-quality filter to not leave behind any coffee grounds.

As a bonus, it makes for a great iced tea or infused water maker too.
