We have been using the brine solution since 2014. Our 2 ponies, which suffer from eczema, have since regrown their manes and now rarely need a blanket.
My Fjord horse has a pollen allergy and our mini Shetland, Honey, has problems with her lungs; they are stable and active. The pair of them have separate open stables, where we have installed a timer for the brine misting - they both voluntarily come to the brine chamber every day when the timer starts. We have been using a second device since 2017. In conclusion: we are grateful for the many years we have used OxygenConcept and the at times incredible success we have had with it.
