Is anyone familiar with Elof Hansson's Solid Exotics line?

I really like their Brazilian Walnut floors at my local retailer but I have not been able to find any information on them when I research them. I read somewhere that they've been in business for 25 years..but that's about the extent of my findings. I'm looking to hear about more about their woods, milling process, feedback, reviews etc. How do they compare to the more popular brands?

Any information would be very helpful.
