I just had a go around with Walmart. Which I purchased an Hatsan Spark, with an extended warranty. Well the fan crapes out after 3 months. Then I find out it’s through 2 and 3 parties and they are tucking it to me. I didn’t drop it, break it or abuse it. It’s made in China, that says it all. Here’s my question anyone know what’s going on? The compressor itself still works fine. If I send it back to Hatsan I won’t see this thing in weeks. I’d like to fix it myself, maybe with a computer fan which is probably what Those People put in. Any info would be appreciated m. Thanksgivings
