Dr Earth Organic Grows

Thought I’d check here. First 4” fan purchase I made, lasted 8 hours before the fan vibration kicked in (haven’t purchased anything from them since) Vivosun refunded me but I still have an excellent working motor. Just need the fan blade as mine was warped. Does anybody have a junker laying around that may want to get rid of the fan blade on. I’d hate to toss if when all I need is the blade. Thanks!
