"worth a try!"
My 16 yo TB mare has been a non-sweater since she was 2. Her previous owner tried everything on the market before giving up. When I bought her a couple years ago, I decided to try One AC again; no luck. This year, I began her on the One AC March 1st in addition to the Perspire Plus. So far on days when it's been well into the 80's, she's still not sweating, but also doesn't seem as heat stressed, either. Something's working (to an extent), so I'll keep her on the Perspire Plus indefinitely and keep my fingers crossed.
