No experience, but most of those items are Preifert 3-pt equipment. Not some of those goofy arena-vator type things (I dont' know who makes those. That could be ABI, but I don't know that). I say goofy in that they look different that most anything on the market, but they may work great. Never seen one in action though.
Just thought you might like to know that it's like so many other things out there today... re-branded. Nothing wrong with that... it is what it is.
Also - It says on their website that they are based in Indiana, but the "free shipping" (and I use quotations b/c there is no such thing as free shipping. You're paying for it somewhere) radiates outward from Texas, where Preifert happens to be made and HQ'd. Makes me think that it may actually be related to priefert.
