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!

Could of been 5 Stars I have found the hammerhead Karoo 2 once you know how to use it after my garmin 520 an excellent bike computer. The mapping is outstanding and the data you can have on the screen is also very good. Its easy to use and you don’t need to change the mount from your garmin mount as an attachment comes in the box. The display is very clear and easy to follow. BUT I can’t give five stars as the battery life is very poor if you have a number of sensor going at the same time as the mapping. After a 2.30 hour ride I was down to 65% battery life. Come the summer am hoping this will last the 100+ miles a ride. I do think hammerhead need to look at this very quickly to compete with the likes of garmin. HOWEVER saying that I would recommend this bike computer as I am more than happy with it.

Fed up with workarounds The unit has multiple shortcomings but I guess these may be different for what you are using it for. I test the basics against an old but super reliable and functional Lezyne Mega C. It sends a live tracking email - Karoo can’t. You have to text a weblink. Lezyne permits a cadence (only) Bluetooth link but Karoo can’t - it takes speed and distance bundled with cadence and then conflicts with its own speed and distance measures - so speed and distance stop at random intervals and gives erroneous data. Lezyne displays a simple clear graphic of the SRAM shifter position. Karoo displays numbers… Lezyne is inexpensive and ‘just works’ Karoo 2 is expensive and needs constant tinkering or workarounds for you to try to justify the costs. Unfortunately I was well through my 45 days when I acquired my new modern ebike with lots of Bluetooth and Ant+ sensors. I have to unpair these to get any sense from Karoo 2. Am just wearied with it…

Masterclass in Comms & Customer Experience Being a young and small company building its production and logistics capabilities, its taken a few months for them to ship product - the Karoo 2 -at scale. At first, I was a little worried. But I shouldn't have been. This company has delivered a masterclass in how you maintain quality and trustworthy communications to keep you informed of where you stand in line for your product delivery. They set realistic expectations and even beat them. The product packaging and unboxing experience beats that of much more mature companies. And then the product itself works right out of the box. If you are coming from a Garmin, then the fact this just works as well as offering a 'next-gen' product experience, it feels like 2007 all over again when I moved from a Microsoft phone to an Apple iPhone. No more slow, clunky interface. And Garmin is notoriously unreliable and their software quality poor. I'm coming from a 1030 Plus, and its no competition. The Karoo 2 is a disruptive product that will hopefully push the overall market to step up its game. And with a customer experience to match, these guys deserve to succeed.

great device and outstanding customer… great device and outstanding customer service bought the karoo2 about a year back and it's a great device. I use it for gravel rides and it's got a lot of useful functions, I love it. It got shipped very fast to Denmark from their hub in the Netherlands, and I also got great customer service. My gps mount broke, and they sent it back to me complimentary right away. After 2 days I was able to get out riding again. Highly recommended
