I have been patiently waiting for my Karoo since early funding late summer 2017. This was my first funding that through and I was excited about finally receiving it via UPS several weeks ago. This Karoo was highly touted as truly the next big thing that was going to give the iPhone and Garmin Edges a full competition experience. The Hammerhead Karoo is built on an Android Operating System has the integration metrics on board 3G cellular WiFi without a phone required. The screen is a Grade 4 Corning Gorilla Glass that allows for maximum visibility, high color resolution 640×480 and 229 pixels per square inch with the largest end to end screen so far. The battery life is 15 hours of runtime and 10 hours of full brightness and Wi-Fi mode. Karoo works simultaneously and seamlessly with all Bluetooth and Ant+ sensors with the high-resolution color screen with full customization of all objective cycling metrics. Easily build, discover and modify any route with GPS navigation system and even I can’t get lost. The Android operating system with 2.4 GHz processor, 3G Wi-Fi, 2 GB RAM and 16 GB of storage. The unit is crafted with aluminum titanium skeleton that has an airfoil inspired tilt for maximum visibility with a rock-solid BarFly for Max melt. As for cost, I paid in the funding around $300 and we have yet to see what the final cost wind up being price will be close to that amount. The Hammerhead Karoo a cycling computer advancement with full customization, integration and visual acuity that will give the Garmin Edge a full run for its money and is one of my early Top Products of the year.
