Review on 🚪 Neoera Door Stopper Wall Protector (4-Pack): 3.15" Larger Rubber Bumper with Premium Adhesive Sticker – White, Ultimate Wall Protection by Anferny Pineda

I don't usually write reviews for products I buy from Revain but this time I do. I felt I should. These wall protectors were very easy to apply and went really well with my light grey/blue walls which was lovely. However, when I applied them, I noticed that the sticky part of the rubber pad just stuck to the rubber part. so 2 out of 5 parts had the adhesive part of the rubber pads not aligned with the rubber part. At first I just ignored it (since I only needed 1 of these) and stuck them to the wall anyway. After 1-2 weeks, I heard a "thud" noise while sitting in the room. I looked around and thought something had fallen off my bedside table or something. It turned out that this wall protection had simply fallen off. Very disappointed, I tried sticking it back on the wall but it lasted 1 day and then fell off again =__= what is this?
