Review (5/5): I've had good luck.
I bought this because Avon stopped selling theirs. I don't think this worked quite as well as Avon's but it still works, just not as fast. I wait until the nails are kinda dry ( so a minute or two?) and then spray. I also try to do super thin coats of polish, as a general rule.
Maybe this doesn't work well with some brands. I've used it with Sally, opi, china glaze, color club, and Avon without issue.
