"I bought them late night on a Sunday and received them no later then the following week. The delay was okay. The only problem is that the tracking number only got updated the next Friday. Beside that the quality is great. same as the one I tried in store but less cheaper. I saved around $100. I just need to get them to the optometrist to change then lenses and have my prescription added. Great deal after all. I don't know for other models but I will be ordering back again that is for sure!!!"
