COROS Launches Dura cycling GPS computer

DC Rainmaker doesn’t like it:

I’ve had the COROS Dura for a bit under a month now, which normally would be enough time to put together an in-depth review – especially the many rides I’ve put on it. But at this stage, the unit simply isn’t ready. COROS won’t have a more stable firmware until tomorrow (June 18th, a day after this announcement), and even then, it sounds like many of the issues I’ve raised will take weeks or longer to sort out.

Again, a bike computer isn’t really the thing to comment on here, but reading these launch notes (not a review!) by DC I wonder what made COROS rush this product to the market?
