Even before launching the Coros DURA had already been projected to “disrupt the market”. The reality couldn’t be further from the truth. “This isn’t ready to launch” was one of the first things I gave as feedback after using this highly anticipated cycling GPS device. In this video I give a first-hand look at how the DURA really performs as delivered for review. Coros now have their work cut-out in getting this unit up to speed prior to shipping it in a few weeks.
