As a Kickstarter buyer of the first Karoo... I just wouldn't. I'm not being a paying beta-tester for the guys at Hammerhead a second time... fool me once and all that. I sold mine a year ago-- and I shipped out a sealed-in-the-box replacement unit, as my original stopped taking a charge just a few days before its first birthday. I still contend that it's some of the best cycling-specific hardware out there-- but the software is pretty bad, and they're still breaking quarter-turn mounts, after more than one redesign. It's no surprise the new one is half the size of the original.

They still haven't gotten the software right-- the battery will still drop from 40% to 0% on a whim, navigation still crashes routinely, etc, etc. And mind you, the Karoo has been on the market for 2 years. I imagine they will have corrected a great deal of the failings of the Karoo with the 2, but I'm not gonna be a guy that pays to find out. Looking at the initial software roadmap from the Karoo release, some of the promised features still aren't implemented. They just added Strava Live Segments this week-- and that implementation looks fantastic-- but at too great a cost, IMO.

If you want a full-featured unit that works every day (read: stable) then I can't see it being a product from Hammerhead, unless they completely replaced the entire software team.
