This is the worst system aviable on the market. Don't waste your money , the unit I received is stuck on 16 % humidity , you have to shake it to even change the humidity levels , my $3 dollar walmart monitor works better 👎

Finally decided to upgrade from my 5 year old Edge 800 to this new Edge 820. So far my opinions are mixed. Overall the product looks like it might be an improvement, but has some niggling faults. I cannot recommend buying one at this moment

Followed all of the directions perfectly. Left the product in my hair for the longest recommended time and my hair is still curly. Buying this product is the same as setting your wallet on fire.

My mother used this on me and introduced me to it when I was about 5-years old. I'm now 62 and am pleased to know that it is still available, although it is a little different now. The old Sayman Salve came in 4-oz glass jars, was made in Savannah, GA, and it had camphor in it along with the zinc oxide. It still has the zinc oxide (and the lanolin) and still works just as well as far as I can tell.
