Not impressed. They don't provide their sources properly, nor the methods those sources use, which means that what's presented is not an accurate overview. Most health authorities update their numbers once a day and there is always a lag, especially with the number of deaths, plus the testing is inadequate, etc, and so the "live updates" thing is merely a gimmick that doesn't mean anything.
If the world doesn't ramp up testing pretty much all of these sites will be meaningless.
