These are some great door stoppers. I like that they can be stacked. One of the doors in my house is kind of high and has hardwood floor. We stacked 2 together and it worked perfectly. The 4 pack is great and makes so we can keep multiple doors open. My kids are little and they don’t need to close doors yet. When my baby has access he closes himself in his bedroom and then gets mad because he can’t get the door open. This door stopper keeps him from moving the door. The grippy design on the bottom works on hardwood or carpet. I have used them on both. They feel like great quality materials were used.
