So... meh? This is somewhat usable in a situation where you might use triple-sec but overall I find it not only a 2-note wonder but the main note I would enjoy the most, the orange, fades far too quickly to just leave a sweetness on the tongue. Mixed in a drink the orange pretty much gets lost so all it does is add a tiny bit of sweetness, it seems to me. It seems to me you'd be better off with any number of far cheaper methods to add a bit of orange flavor to a cocktail that than to bother with the expense of this just to have something that you might be able to use as a 1:1 substitute for triple-sec. This one is a "pass" on buying again for my NOLO cocktails.
Thinking this over a bit more, to be fair, Triple Sec, which this would presumably be meant to be used in place of, is a more mild orange flavor, it's not Blue Curacao or Cointreau or the like. So in a sense perhaps it follows suit to some extent. Even so I stick by my rating here simply because the orange seems to only be noticeable up front and then disappears so quickly into just a lingering sweetness without the orange at all so it doesn't really do the job the way I would like it to.
