I would research it further, but only because the company is in the hook business.
But, I am surprised, because most inexpensive rings are, I think, formed of seamed tubing, and the weight rating seems high for steel tubing with so little meat. Seamed tubing may not show the weld, but the seam is weak.
What this must compete against, as a fixed multiple-connection point, is a lightweight Amsteel loop. Could be plain, or could have a thimble in it.
Edit:
For a rule of thumb: Amsteel replaces hi-strength steel wire, diameter for diameter, in many industrial settings, and at about 12% the weight.
AmSteel®-Blue is a torque-free 12-strand single braid that yields the maximum in strength-to-weight ratio and, size for size, is the same strength as steel—yet it floats. <snip> making it an excellent wire rope replacement.

A 2" diameter spliced loop would use about 16" of 1/8" Amsteel Blue and have a breaking strength of about 2400lb. (Not twice that, even though it is completely doubled, because of weakness at the end. It would weigh about 4 grams. So, comparable strength spliced steel might weigh about 28g, 1 oz. Now, we're getting close to the weight of the lightest climbing-rated carabiners.
I like the Amsteel Blue continuous loop, instead of the steel.
