OK, since you asked, the Website doesn't work well on my Apple Mac pro running Mojave iOS 10.14.3. That's pretty much up to date. Their AgFolks site isn't working well enough now to show off their products - which do look interesting from what you can barely see, but hard to figure out just what they are, or supposed to be, or even just how they are supposed to work.
The web site needs some work. It crashed on me - which I haven't seen happen in years. So it isn't yet completely stable. There is a kind of dark overlay on the screen which gives the effect of trying to look through a dirty window, and there's some sort of pulsing light in the center. Internal links may or may not work....it's kinda hard to tell. See attachment below.
Bottom line is that they need to put some work into the website. Right now it's not good enough to evaluate their products.
I'm sorry to the bearer of bad news on the website effort, but glad to hear you are impressed with their grapple. I also prefer the double clamp style. And from what little I can see, these seem well built.
