A Pocket Sized Phenomenon
What a superb, easy-to-use, so-many-data-variables, integrated-with-everything device! I love it and can’t imagine a better cycle computer. The user interface and screen quality are outstanding, and the new mount makes it feel very secure on the bike. Can’t fault it.

So Far, So Good
Just received the unit the other day and took it out over the weekend. What a great unit! I have had two different units over the years, Garmin & WAHOO Roam. The Karoo 2 is far superior in my opinion. And to top that off the customer service is on a much higher level than anything I have experienced. I would highly recommend this bike computer!

I Love My Karoo 2
This is my first cycling computer and I love it. It was very easy to learn how to use and setup. I love the simplicity of the user interface on both the device as well as the Hammerhead dashboard. Highly recommend the Hammerhead Karoo 2. I'm absolutely obsessed with the Karoo 2 and it has made me even more motivated and excited to get out and ride more! 10/10. 5 Stars, zero issues or complaints. I can't wait to see where the future updates will take us because I know it's only going to get better and keep improving!

Best Cycling Computer Out There
I owned another brand of computer but HAD to move to Karoo 2 after seeing what was capable of and the number of features available, specially the climbing/mountain features and information it gives you to prepare for what's coming! It is clear and delivers what you really need at the right time. I live in Asia so trying to get it here was a struggle and took some time, it would be great if they were shipping to this area, as I'm sure there will be a lot of customers. I'm very happy with the computer and periodically updates that make it just even better! Congrats and great job to the design and engineers of the team!
