I bought this via Prime for my L5 disc herniation with sciatic nerve pain. Unfortunately, it took nearly 2 weeks to arrive! Problems with the carrier and I couldn't track the package as it wasn't updating. Very frustrating as I needed it ASAP!Besides that, it's good quality. Good size for my lumbar back area. One negative is that when you get it out of the freezer after a while the 'frost' starts melting and it gets wet. Always need to use a pillowcase or towel. My other cold pack I have has fabric on the outside and it's frost free. I like that much better. When you are in severe pain you don't want hassles of having to wipe down the cold pack.
