I purchased a pair of used Vortex 8X42 Sidwinders off E-Bay in 07. I tried to take the best of care. Season opened on 10/09. I pulled them out of storage a couple of weeks ago and cleaned them up getting ready to hunt the following day. I set them on my box freezer in the garage and went in the house to pick up my tags. When I came back out(only gone 5 minutes), my dog had pulled them off the freezer. When they hit the concrete floor, they broke in half. She proceded to chew up the rubber coating. I contacted Vortex to see if they could be repaired. Vortex said to send them in and they would take care of things. Turnaround time was less than 5 days. They couldn't repair my sidwinders, so they sent me a new pair of Dimondbacks to replace them. The best Customer Service and Warranty I''ve ever seen. Great company and great product. Best investment I've made in a long time.
