I recently received a pair of Fast 8 divers for another open baffle speaker project I'm working on and intending to review. Upon receiving the new drivers, one of them appeared slightly damaged. I then contacted Lii overseas by email and they responded in about a day which was very quick. After explaining the situation along with a few pictures to Weiyu, Lii immediately sent out another pair without hassle. Each shipment came in literally just a few days, I was amazed. Anyway for those who ever wonder how the service is with Lii Audio, these guys are really wonderful and stood by their product. Thank you again Lii Audio and I love your speakers. When I'm done, I'll post a video. I'll be sending the other set of speakers back for them.
Happy listening!

Thanks Daniel for your demo's and input. Received my F15's today after eight days via UPS. Box was in good shape.
