I used to like this item. The last time i bought this item, it was infested with some kind of tiny mite. They sent a replacement wich was nice, but this time i put the bag in the freezer just in case. I pulled it out of the freezer (two months later) and set it out to defrost. When i came back, billions of little mites were crawling out of tiny holes in the bag FREEZING DID NOT KILL THEM. I do not know if they are harmful or not, but I certainly do not want them crawling on everything.
