Based on those "tests", I wouldn't take it into inadvertent or forecast icing conditions. Sounds like a promising product, but I'd like to see it properly tested. I think the right way to do this would be to use an aircraft certified into known icing conditions, so any encounter, inadvertent or known, is a real test, not to mention there's an "out" at the same time. This technology is great and it needs to be accelerated IMO.
