I bought it last summer and I absolutely love it!
I use it all the time!
We do our own hooves the "Pete Ramey" way and while this does not replace all the regular farrier tools it helps out so much in between the trims I can't even begin to tell ya.
I use it about once a week on all three of my horses. Just a couple of swipes and done! It keeps that mustang roll perfectly.
I also bought the black one, can't remember what they called it. I've only used that once or twice. It's supposedly can be used to do a regular trim.
The black one is not on my love list though. I suppose if I worked with that one longer it would get better.
A few years ago I also bought the Riders Rasp, that has been collecting dust since about day one. Waste of my money, but, the Rider's Rasp gets a thumbs up from me.
If you have the money I think it's worth it.
They have a shipping sale on their website today so I ended up ordering some replacement blades.
The only consideration would be the blades. They do last awhile, but, they do have to be replaced.
One last thought, I would not buy any of the other things he has for sale like the sole thing or the polisher type thing.
