It was pretty good. I think I even broke a sweat.
It was very warm
I've used a similar product from another manufacturer, but it didn't seem to have any particular effect.
It was slightly thick, and I could feel the bath salts soaking into my skin even after I got out of the bath.
I really felt the heat retention effect! I felt like I was warmed to the core, and it was great to be able to go to bed in that state. When I use this bath additive on legs that are completely exhausted after a day of standing at work, I feel so much better when I get out of the bath!! I feel so light!! My legs reach their limit every day, so I want to use this every day to relieve them. The water becomes a little cloudy and soft. There is no scent. It dissolves a little slowly.
