I haven't used the media in my evap cooler as yet. This describes my purchase and delivery of product only. The lead time for the order to ship was very long compared to most other vendors. This wasn't a problem because I ordered long before I actually needed product. The price was about 15% higher that similar product 2 years ago. The media was boxed in exact sized standard strength cardboard box and of course as with any shipping company it had a hole the size of your fist in one side and all corners were dented. The media was damaged because there was no other packing to help absorb any rough treatment. I don't expect the damaged edges and corners plus the dent to be a big problem with actual use.
