Karoo 2 Bought a Karoo 2, it factory reset itself three times within the two weeks of owning it, so spent a lot of time logging back in and having to waiting for it redownload all the maps... On the third time I raised a RMA, which was a pretty quick and slick process. Would I recommend a Karoo 2? No, at this time don't think the software is mature and stable enough. Would I say they offer good customer service?? Yes

Exceptional customer service response to Karoo 2 issue As with others - just wanted to recognise that Hari and the Hammerhead team were absolutely brilliant in responding to an issue I had with my Karoo2. They went way above and beyond the call of duty in helping out and sorting out an issue I was experiencing. Beyond that, they were extremely generous in resolving a separate matter. This isn't the first time that Hammerhead have responded in this way, and it is a key reason why I choose to stay with the Hammerhead ecosystem. Thank you all so much!

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.

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

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…
