Actually, they were not TESTED in the real world before being put on the market. I was one of the first to buy and the ones I got did NOT have radiused holes - not suitable for use with soft shackles. I tried to radius them myself, but was not acceptable. They are now gathering dust in my "mistakes" box.
Later version was radiused, so good for those who received them.
HTH
Wanna sell the ones you have in the mistake box? I have no use for soft shackles and would only ever use a chain with a hook or steel shackle anyway cause i have loads of them from work.
