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.

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

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.

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
