We do use a high quality Grade 80 steel which takes a smaller amount that results in a lighter weight. The holes result in an even lighter weight.
Like I said, cheap is not us. We don't try to come up with ways to design a product to be the least expensive, we want to offer you the highest quality product at a reasonable price.
We can do that because we have no dealers, distributors, on the road salesmen, big flashy trucks on the road, printed advertisement etc. that is factored into the price with other "high end" products.
If you do a side-by-side comparison with one of our attachments and a comparable priced big name attachment, I guarantee that ours will beat it BY FAR.
If you have a taste for quality, do the same with a cheap product vs. ETA and notice the difference.
There's a place in the market for all kinds.
