+1 I also never had a problem with it.I've only had issues with IO not melting when I got moisture from splash in there and the salt became hard. Then it doesn't dissolve fully quite right for some reason.
I'ved used it for 7 years and minus getting moisture in the bucket, it never failed to dissolve for me. Roughly a few minutes to fully dissolve
It seems to leave crazy thick white residue in the bucket that is hard to clean out also. (after drying),, and the water is always cloudy.
