Rumblers Extraordinaires,
This holiday season, we're paying homage to our Kickstarter roots and offering up a limited edition bottle as an add-on for the Rumble Go filter. The bottle might look kinda familiar since it's the same one most of you own from our 2018 campaign (and seemed pretty happy with), except this is the XL version with a 34oz capacity instead of 20oz.
Up until now, we've just been offering Rumble Go in a filter-only format and giving folks the flexibility to use it with whatever bottle they choose. Of course that standalone filter option is still available, but for the holiday season we thought some folks might find it a bit more giftable if we offered it as a complete road-ready brewing kit, similar to our complete at-home brewing kit Rumble Jar.
Seems like a pretty solid holiday gift idea if we do say so ourselves! And if you're interested, we'd like to make it even more solid by offering up this $5 discount code (active now through the end of Monday 11/30): NEWRG34
New! The Original Rumble Jar (just without a jar)

A quick update to our Rumble Go Gang to let you know we released a new product yesterday! It's the same 32oz filter from the Original Rumble Jar (our first product), but now it's finally available in standalone form. All this means is that you no longer need to buy a Mason jar along with it.
And of course there's a discount available for you, in case you're interested in expanding your Rumble portfolio. Use discount code NEW32 at checkout to take $3 off the standalone 32oz Rumble Jar filter, now through this Sunday 10/25.
We'll be launching a couple more new things over the next couple months (one of them Rumble Go-related!!), so please stay tuned to these updates since we'd love to have your support!
We'd love your Rumble Go feedback please! It's just a 1-2 minute survey.

Have you been using your Rumble Go?
We'd love for you to tell us about it! Some thought-ticklers below to get those wheels turning:
What's gone well? Is it part of your routine?
How's the coffee?
Pretty straightforward instructions/brewing process? Anything leave you stumped or confused or annoyed?
Where are you using it? Situations/locations/activities.
Any jokes you'd like to share? Doesn't have to be about coffee.
Fun Backerkit numbers
After poking around in Backerkit, we uncovered some fun Rumble Go project stats that we thought we'd share.
Stat #1 has us really thankful for shipping carriers doing what they do...
Stat #2: Almost an even split between Dark Black and Orangey-Red caps/bases. In terms of bottle colors though, Dark Black was preferred 2-to-1 to People's Purple, and Brewberry Blue landed right in between.
And finally, stat #3 really just serves as a friendly reminder to the 3% who haven't filled out their surveys yet. Do it please! There's one waiting for you in the inbox associated with your Kickstarter account (search your email for "Rumble Go Backerkit" and you'll find it).
Rumble On,
Hans & Karl
Reward fulfillment finished up last week, so now tell us EVERYTHING!

Your feedback pretty please!
All the Rumble goodies shipped out to our last remaining Kickstarter backers last week, so with a few exceptions (mainly internationally), that means almost all of you have Rumble Gos/Go's/Goes in your possession. US-based folk, the scheduling gods gifted many of you a 4-day weekend starting tomorrow (WOOOHOOO!!), and that seems like an ideal time to get outside and kick the tires on some portable Rumble wares. So pop those filters into your water bottles, brew up a batch or two, and tell us how it goes. We love hearing what you find...the good, the bad, the strange, the innovative, the humorous. Feedback time is always interesting, plus we like hearing from the people who made it happen!
How can you give feedback? Message us on Kickstarter, use the project's Comments section, send us a note on our Contact page, DM us on social media...they all work and we read them all, so however you feel most comfortable reaching out is fine by us!
Wanna follow us?
We're doing our best to build up our social media stuff, so in case you'd like to stay connected and you could spare a click, we'd love to have you follow us:
Fun update to our inadvertent product durability test
Rememeber those crushed filters from the last update that had an unfortunate run-in with a forklift? One of them magically popped back into shape the next day (second pic below). Now if this isn't dent-resistance, I don't know what is!
before: two crushed
after: 1 still crushed, 1 magically uncrushed itself
