Having owned the Karoo 2 since it was released, I became a big fan of the Hammerhead system. Favorite new features of this latest version, simply called the Karoo, is the amazing screen. Much easier to see in daylight. Secondly, the buttons are easier to press and quicker to use. The battery life is also much better thanks to the auto brightness function. Louder alert beeps make it easy to hear and the quicker processor makes the unit snappier overall. That said, there is still some lag when using the touchscreen, but not enough to be a problem.
This model is a big upgrade that I feel is worth it.
The display is beautiful. Colorful and easy to follow navigation. Battery was still 35% after 3 days of riding in Death Valley and didn't charge it once. Very intuitive setup and simple map place from ride with gps. I've had several different Garmins and this computer is superior on every level. Buy it.
Sdk not enabled so useless with Shimano equipped bikes. Very poor battery life. Slow. Nice screen but some questionable ui decisions like tiny fonts. I don't know what sram is thinking releasing it like this.
This was a huge upgrade from my Garmin 530. I think the UI is the best out there, especially for Strava live segments. No bugs or issues yet, very simple to get going. Get about 13 hours of battery life.
I've been using a 5 year old Wahoo Bolt up until I got the Karoo. It is more simple to use and does SO much more without needing a complicated manual to figure it out. I'm enjoying it a lot. I do wish that it had a mounting system that was more compatible with all the mounting systems I currently have.
