How much thickness does it add, would you say? It's hard to tell from pictures. I'm looking for a much thicker feel than the original. I've read differing reviews on these wheel covers; some say they work fine others that they slip on the wheel when you turn it. How's the feel? Also, I'm thinking "Made in China = sweat shops, poor quality in the long run, and carcinogenic materials in the leather" but I might be overthinking it :-)

All the best
