"I had a good experience with OPT when Mike W. handled a trade-in of my old equipment for the purchased on new equipment. I did not want the hassle of trying to sell my old equipment on my own, I also knew that I can not expect them no make profit on the exchange. Mike W. was straight forward and helpful. I had no complaints about the service I received. I did most communication through email and had no complaints about communication. I ended up returning the Finder Scope I originally got for another model Finder Scope. There was no problems in handling this transaction by email."
