Their stock of parts for any glasses over a year old is dreadful. They’ll even tell you to look at aftermarket lenses.
The factory in Irvine CA used to be brilliant. You could go in to the service desk, drop whatever you had with you off and they’d refurbish it there and then – including my brother’s time bomb watch. You’d get free replacement ear socks, nose pieces and massive discount off lenses, which they always have stock of.
Now, unless it’s current stock, you may as well not bother. Lutoxitter have really shafted them. The “factory” is now merely an assembly shop for Chinese tat with an overgrown pump track in the car park.
