I bought my first scope only 8 weeks ago, C8 Edge plus some accessories including Dew Shield and Dew Controller 2x. The first time setting up I found the Dew Controller dovetail clamp was defective. Celestron quickly gave me a same day RMA. After 3 weeks, no replacement was yet available. I met a customer service rep at NEAF and mentioned my problem. Few days later the RMA deparment informed me that new shipments were uncertain and pointed me to a vendor who had stock and promised me a full refund check, which arrived today. I think that is about the best customer service I have seen with any product, big or small. I hope the trade tariffs don't change this kind of customer first thinking.
