Bought a karoo2 two weeks ago Bought a karoo2 two weeks ago, battery life was very bad.Contacted customer service which I believe is in India and those agent were not interested to arrange a refund instead,they were forcing me to go through troubleshooting which I have already done but to no avail and when insisted for a refund ,I'm still waiting for their reply and very disappointed with the unit.Got a Garmin 1030 plus which is way better and user friendly.Karoo has been hyped up with lots of adverts,don't fall for their trap.

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.

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.

Poor The fact that the 5 star reviews all seem to be customer service related doesn't bode well. Trip computers don't need customer service. I have a Karoo 2. It's badly thought through and is forever scuppering my attempt to record rides. It's real "emperor's new clothes" territory. Avoid.
