Amazing computer, amazing company I've always disliked Garmin EDGE computers, but until the last few years there weren't many genuine alternatives. I've had several Garmin computers - 500, 510, 705, 1000 - all of them were buggy, had a poor user interface, slow to operate, and had issues with Garmin Connect. I tried a couple of times to ditch Garmin. I had a Polar v650 which was nice, but bricked when passing the military base in Mallorca. I also had a Bryton, but it had an even worse UI than Garmin, and didn't like rain. Most recently, I've had a Wahoo ELEMNT, which is a fantastic alternative to Garmin's EDGE computers. Last year though, despite being an advocate of iOS and Apple products, I plumped for Hammerhead's Android based Karoo 2 head unit. Hammerhead pay nearly as much attention to their packaging design as Apple - the boxes are well designed, and unboxing is part of the experience of ownership. Unlike Garmin, there's cheap looking printed glossy external boxes with fluted brown internal sections - everything is matt board with spot UV logos. It all feels very premium. Which is should do given the cost of the device. The Karoo 2 itself feels more like a premium mobile phone than a GPS bike computer. The plastics are high quality, everything is nice and tactile - a bit like a Wahoo ELEMNT in that instance. The screen display is bright and crisp, and it's easy to read everything even with my ageing eyes. As a UI/UX designer, I'm always picky when it comes to human/computer interfaces. I am easily frustrated by some of the poor UI design that we all experience on a daily basis, so any new bike computer has its work cut out to impress me. This is where the Karoo 2 excels over the competition. They've paid attention to the UX/UI design, the interactions are smooth and well thought out, and it is a breeze to use. As I say, it's built on Android, so unfortunately there are some obvious Android system screens in there but it's a small price to pay. Rather than building their own OS, Hammerhead have used a proven platform to build on so they can concentrate on their cycling specific features. The other thing about Hammerhead is they run their software side like a proper software company, and seem to adhere to Agile methodology. The release new updates often, and continually improve the features, functionality, usability, and interface of their product. I didn't ride outside over the winter (I have asthma and it makes it difficult for me) so I didn't use my Hammerhead from September until April. Turning it on in April there were updates to run, and there were multiple new features and updates added. I also experienced their customer service when my mount snapped. I contacted their support team, and within 2 working days I had a new mount free of charge under warranty. Ultimately, the Karoo 2 may not have certain features that Garmin users have, as Garmin is a more mature company. However, Hammerhead clearly have a backlog in place as they regularly update their firmware, and you can request new features and report bugs via their various support systems. One of the features I wanted was a climber function, and sure enough they have released one. If the Hammerhead has the features you need to use, then I'd seriously recommend ditching whatever you have now and going for a Karoo 2. Great computers, great software, great customer service.

Excellent Customer Service Just have to say that the customer service provided by Sumit at Hammerhead UK has been superb. I purchased a Karoo 2 from an online seller and the device had an issue with auto-scrolling on menus which looked like it was due to a faulty button. After issues processing the return with the online seller I reached out to Hammerhead UK. They very kindly agreed to provide a replacement and this was completed in a matter of days. Can't comment on the new device as I've not used it yet but I wanted to recognise the excellent customer service that I received.

Karoo 2 Explore with ease with the Karoo 2, and upload workouts from TrainingPeaks. No more stopping and more time riding.

Karoo really look after their cutomers I have had this excellent cycling computer for about a year, and always love updatng it to see what new features are available. Over the weekend i updated the software and device locked and stopped responding. Hari at support was helpful and suggested few things to try and resolve the issue. In the end he authorised a replacment unit which arrived in just 2 days. Happy cycling again!

I am a very happy Karoo 2 user I am a very happy Karoo 2 user, for one year. I had some questions, got quick and qualified answers, so I bought Karoo 2. For me, the Karoo 2 was, by far, my best buy the last couple last years. I have used several other cycling computers, but no one matches the Karoo
