I have a different product in my own ring at home, but was boarding last winter at a place that added the ReitenRight to their indoor. I thought it made a nice improvement over the previous just sand/screenings that they had in there. It did not, IMO, add to moisture retention at all. They still had to water every morning and on days that they did not, it was horribly dusty (very busy ring so it dried out quick just due to all the activity). Not blaming that on the RR, just saying it didn’t help. I don’t know if they offer more than one product type, but what was used was described to me as “torn up yoga mats” and was multi-color rubber-y pieces. Because I wasn’t paying for it this time, I can’t tell you the mix they used or anything. I know that trainer has moved to another barn and is putting this same footing in, so she must be happy with it!
