It's comparable indeed.

One big advantage over things like 'superglue' that spontanously polymerizes is that you can apply it carefully as a liquid, check if everything is good, and only then decide to cure it into place with UV light.

That said it does not care about the source of the UV light at all, and will probably set from exposure to direct sunlight as well, so tinker with this stuff only indoors and away from windows as a decent amount of UV will make it though a common window on a sunny day.

I Tested it in sunlight yesterday and successfully bonded 2 broken pieces of window glass together after leaving it in the sun for ~3 hours. Give or take a few small clouds.
