Evans waterless Coolant

[pistolpete]

I am going to be changing my coolant in the next few weeks and reading various posts , it seems the waterless way seems to be a good way forward, for those who have done it , does it seem to work well and trouble free. How do you drain ALL the old water out, as this is not an issue really when your just changing water and anti freeze

Seemed like an honest review when I watched it.
