Love my walker! Could never live without one after having one!! Mine is a HotToTrot or something like that... Older model but runs very very quiet and smooth! I believe it is 1/2 horsepower 4 speed with reverse and I put 4 horses on at a time and will walk them or slow jog.
I currently have a Supreme walker and I really liked using it, but it isn't working now. I don't know if I should try and have it fixed, or look at purchasing a different model/brand. I love having it for warming up and cooling down the horses. I don't use it for conditioning.
K I don't have one... But been seriously considering and researching them for a while now, and I just love the Preifert's Free horse walker! As far as getting a walker for conditioning perpouses, I think the free horse walker concept is really the best! and not to mention it is belt free so it's supposed to be a lot less maintenance issues.. But that's just from my research as I said I do not have one.. Yet;))
