Fitted in about 15 mins. No messing around. You don't have to chop anything so if you want to put back to standard you can and you get a little number plate light.
I've got the Rsend kit, with a 7x5" plate, makes the rear a lot tidier. I've had no problems with the plate falling off, although it doesn't feel the most secure of installations!
With the plate relocated, the lights don't look to bad, I think they're in keeping with the style of the bike, but if I was to choose, I'd go for the Kens Custom Lights Conversion with built in indicators
I had the Casoli one on my 749(the big red one) for 2 years without problem just use loctite on the number plate bolts. Just ordered one for my 999. They also do a led light which im going to order.
