Order was received in a timely fashion but not sure what is wrong with the contacts. I order often and have for a few years now. Too many of this batch (and the last) were not comfortable, they were either rolled in the package and seemed to get a crease or there was no visible defection but after only minutes were uncomfortable and had to be thrown out and wasted. This time the problem is with the -4.00 and last time it was a more of an issue with the -4.75.
