I received this model that immediately seemed dull.
After 10 minutes, the disaster, the surface layer Decole. (See photos).
I almost return (I filled the form), but as I really needed it, I decided to polish them to remove the surface layer.
After 15 minutes of effort, I have a pair 'repaired' a great comfort.
Damage to buy French at this price and having to finish the job.
Friends of Amazon, a small drawback would be welcome!
