Kids and I are nearly finished. Mind you it is in black primer, and we decided on a silver seat cowling. We're undecided on the silver cowl. I didn't have any real issues with install - it is pretty straightforward. A couple of very minor adjustments to make it fit better in a spot or two (key tumbler was tight for one, and bolting the supplied tail light in was a little difficult, but taking my time I made it go in quite easily).
Most difficult part for many will be paint. I painted ours with primer and a single coat of matte black to make sure that's what I wanted on the bike. I'll disassemble and have properly painted now - and will likely stick with a semi-gloss black as opposed to matching the gloss black that is the factory paint.
