i sent in 2 waterblocks and the motherboard that was damaged as i was told they would replace it. I also sent them videos of the waterblock leaking , spent 300$ shipping it i was told it would be refunded . weeks later i recieve a package with 50$ duty i thought it may have been my items have been replaced but no they claim they were not defective even though i presented video evidence ,. also keep in mind it took almost 6 months to get them to the point where they would even accept this rma . horrible service and would never recommend anyone i know to use there products
