I bought this to prop my kitchen/laundry room door. I can't even use it in my house because it's very toxic. It smells like really strong melting tires. You might also think that since it's rubber it would stick to the ground to prevent a heavy door from closing, but it's not sticky at all. This wedge simply glides across the floor when the door is closed. Definitely not worth the money if you use it for a door wedge.
