This is a high quality product and easy to follow instructions and images. It is designed for specific types of windows so I kept that in mind when choosing this design. Good value for the price.

Living in a townhouse without air conditioning, I had to add a portable Air conditioner in my bedroom and this kit secured the air conditioner unit and totally keeps hot air out!
