Did a lot of research before purchasing this cover last fall.  Worked well last fall and winter, everything seemed fine in the spring.  Did not use the fire pit over the summer, but the cover was down to the ground, nice and snug.  Opened it up to use this fall and the pit was full of water and the bowl covered in rust.  Condensation on the underside as well.  No rips or tears in the cover and the cover never came off the pit.  Very disappointed in the product.
