Hammerhead NavigationReviews of hammerhead.io

Karoo 2 was good for a while. Then the next model came up, and hammerhead abandonded their existing customers. There are massive glitches, for instance: the position arrow in the map completely disapears mid ride. Or, when is there, it gets completely covered every time there is a turning indication or a hill profile. Yet, the response I from the team is “we no longer roll out software feature updates to the Karoo 2 unit”. It is also shocking that Hammerhead does not enable compatibility between the headset and SRAM (Force/Red) given it’s a simple development, and SRAM is the parent company. After 4 years with Hammerhead I had enough: when product developers abandon their users, users abandon the products.

Absolutely happy with my Karoo 3

I bought a Karoo 2 some years ago. The battery performance has been uniformly terrible. The almost constant software updates with seemingly no difference are annoying. Not as annoying as using it in heavy rain last weekend when is simply stopped working completely. I would not recommend it and I look forward to replacing it with another supplier.

Karoo 2 usb port melted during charge. Support offered no repair options just the ability to purchase a new one! They also warmed me not to attempt repair! These devices are expensive so having the only option to buy a new one is bad.

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.

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…

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.

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!
