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.

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 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!

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

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.
