While we’re loving the no-reservoir design, we should warn you that this means that you will have to stand at your sink holding your Bobble jug while it filters in water from your tap. Unlike a Brita, you can’t just fill the reservoir and leave it on your counter. The filter is relatively fast so it’s not too much of a pain to hold the jug under the faucet for a few minutes but you won’t be able to turn your tap on full blast without the water spilling out from the top of the pitcher. This is the main con of the Bobble jug.
Another less than desirable design feature is the small cap that covers the spout of the jug. While it has a hinge, it has to be manually opened in order for you to pour your water out and if you try to pour it while it’s closed, only a tiny trickle will come out. But it seems like this would be an easy tweak for the designers to fix this small issue.
