If I could give this product zero stars…
If I could give this product zero stars I would. I bought this as a gift for my boyfriend for Christmas, he ran about 3 kg of filament through it and the nozzle would not hold its temperature. I was told sorry for your luck. It's 30 days passed the purchase date. I would not recommend this company to anyone. Their customer service is crap. I would say don't buy from flash forge. Go somewhere else, buy something else. DO NOT WASTE YOUR MONEY...$350 for nothing...I am also contacting the BBB.
