What's your opinion of, or experience with, potassium chloride as a salt (sodium chloride) substitute?

This isn’t really an idle question about salt substitutes.
One of my favorite seasoning blends is Cavender’s Greek Seasoning.

I knew they made Cavender’s Salt Free, so today I sought it out. I was expecting an all herbal blend, but instead they have substituted potassium chloride for the sodium.

I’ve not been impressed with potassium chloride in the past, taste wise, and I’m not certain as to side/health effects.

Do you think I should give it a go, or steer clear? Why?

Diamond Crystal Salt Sense was the only pure salt substitute Consumer Reports recommended.
