Disclosure: I am a huge fan of glitter nail polish, and of red, and this is a red glitter. I'm disappointed that I don't like this more. I really, truly expected to love it, and I just don't.
This is a very blingy polish of mostly fine, red glitter (in the true red to warm range), and slightly larger silver glitter flecks. It looks utterly gorgeous in the bottle, but on my hands, it's actually kind of gaudy (and for me, a lover of blingy polishes, that's saying quite a lot!).
Application is a little tricky, I found, and if you try to put on a second coat before the first is dry (at least, I think that's what was happening), the polish simply will not set, even with a quick-drying top coat. I ended up having to redo several nails, and one of them had to be redone twice. I've never had this issue before, so I don't know what caused it, and it wasn't even every nail, so the only thing I can think of is that I didn't let it totally dry between the coats.
This is definitely opaque, and foil-like when dry. You can get full opacity in one coat, but you need to be careful in applying, because the formula is such that it will drag and push the polish/glitter that has already been laid down if you're not careful.
This is not a horrible polish by any means, but I can't see myself wearing it regularly (and I do wear full on glitter polish quite regularly!). It would be a nice Christmas touch, I think, or maybe some special evening out where ultra-bling is the order of the day, but other than that, this is going to sit in my collection mostly unused, I'm sorry to say, and that surprises me, given my deep love of both glitter and of red...
