I bought this product to go in the playroom for my kids. The walls were new construction - painted drywall. It took me about an hour to stick them all on - they are in individual pieces, so for "A", there is the ant sticker, the capital A sticker, the lowercase a sticker and the word "ant". It was a little tricky trying to get them all level, but it looks good and I just eyeballed it. They stuck wonderfully. I even peeled them all off and repositioned them after I placed them because I wanted to space them out differently, and they are still sticking well. There is one little corner of one letter that is peeling up a bit, but you can't tell unless you're looking for it. And to be fair, I think I peeled that sticker off 3 times and repositioned it, so it's probably my fault and no fault of the manufacturer. The colors are bright and cheery, the animals are cute. My kids were really excited to have something kid friendly on the walls - I was excited that when they outgrow the preschool/early elementary age, I will just be able to peel them off and decorate with something else.
