Swarro, Leupold & Vortex all bend over backwards too take care of the customer. Some of the others are pretty good and some just stink.
I have told all three to invoice me for damage that my kids or I were responsible for and have never been able to get them to take my money for a repair. Leupold has gone so far as to send me a binocular case at no charge that I had asked about purchasing.
