Anybody tried Browserseal cross browser testing app?

I came across this Browserseal cross browser testing app which looks very promising, but I’ve never heard of them before. I’d like to use it to automate some cross browser regression tests.

Anybody tried this tool already ?

BrowserSeal SPAMs to promote itself.

BrowserSeal didn’t even check it’s own website at various viewport dimensions.

I would NOT use BrowserSeal.

Anything that needs to SPAM and doesn’t bother to keep their own house clean isn’t worth my time.
