I've used it for years.
I started using NoSalt in my 20s. I was dating someone who salte his food before tasting it. I had put NoSalt on the table next to the salt shaker. When I suggested he try the NoSalt, he refused, saying that it didn't taste right. When the salt shaker was empty, I filled it up with NoSalt. I put the NoSalt dispenser on the table, next to the (NoSalt) "salt" shaker. He used the NoSalt out of the salt shaker and couldn't tell any difference. It's all in how it's presented. Please note that I, personally, don't add "salt" to my cooking and only add "salt" (ie, NoSalt) to a few foods that I really love a salty taste on.
