We've used them in rental houses and they definitely come off without damaging the paint. I think they are a great idea for rentals, and also for kids who's grow up so quickly. A nursery can easily be made more suitable for an older child by changing the wall stickers. The latest in our home is dinosaur stickers - no doubt there will be a new flavour of the month down the track but with stickers redecorating isn't much of a problem.
