It's an amazing piece and absolutely worth its money. Took me some time to figure out how to arrange the branches since we only had a certain area to fit it into, but after that was set, anything else was just a piece of cake. My daughter loves it in her room and we do, too.
We put this above the crib and it wasn't too hard to apply. The stickers come in sections so you need to pay attention to where the letters go from the picture that is included. We also used a level to make sure it was straight. Definetely need two people to help put this up. But if you screw up the sticker comes up easily to reapply. The only complaint I have is that it is sometimes hard to read it in certain light due to the light reflecting off of the stickers.
