First of all bad costumer service.They have some certain things that they say to all costumers and thats it.No solution to your problem,nothing!!Its like you talk with a machine that repeats the same things for different cases over and over again.Secondly the worst returning policy I ever experienced.I order a pair of studio monitor and it was defective!!I told them that its very important for my job to get the new speakers very soon .They said that they had only one delivery option first with Hellenic post and then with DHL- Deutsche post.If I knew that its gonna take 1 month from Greece to Germany (I receive things from US in 2 weeks) then maybe I would keep the speakers and try to fix them here in Greece!!!
