Cheap leaf springs?

This is exactly the route I first went believing it was the best springs for the money and these are the springs that one came with the main leaf arched backwards the last 6 inches. I argued with Mancini for over a week, with them telling me they could not see the problem in my pics... you can see daylight between a straight edge and the bottom of the spring it’s that obvious...

That is why I went to Espo springsnthings , and believe me, you can see the difference. I did the math and Espo was only about $20 more than the Mancini springs but when I set the springs side by side in my garage the Espo springs looked twice as expensive as the Mancini. Or rather it really brought to attention the poor quality of the Mancini springs. If anyone would like to see the side by side pics I would be happy to show them.
Yes, I would like to see them please.
