It's about as good you can get for not being a genuine Pandora, and it's WAY better than one of those cheap generic beads.  It's pretty and fits my bracelet well.  Similar in size to the glass Pandora beads, maybe a teeny bit larger, but not enough to really notice.
The bead I received is not as well done as the one in the photo, but it's still OK.... the design is not gloppy or blurry and the colors are vibrant/beautiful... exactly the same shades as seen in the photo.  The inner silver piece doesn't poke out too far, it's smooth and lays nicely against my other beads. Perfect as a filler/spacer bead between two silver beads...
