It’s a No from me.
It’s an undeniably attractive unit and touch screen operation adds a new and much-needed dimension beside the time-honoured button pushing. But there is a major failing: a tiny 15 hour battery life is very poor compared to e.g. out of many, the iGSPORT iGS630/630S, or their just released, “Karoo Killer” iGS800 (50 hour battery life), never mind Garmin and Wahoo. Hammerhead is not concentrating enough on endurance level battery life, just features. Progressive updates will no doubt address shortfalls with the K3, but until then, alternatives exist and they pack a punch.
