I'm pretty disappointed. Got mine today. The build quality is not very good. If you gently shake it you can hear it rattling. Pretty sure there shouldn't be any moving parts in there. The tolerances between the various parts are also not very good. The logo looks like it was screened on by someone with the shaky hand but I think maybe it's supposed to look like that for some reason. To top it off Windows 7 hasn't been able to connect to it stating "This device cannot start. (Code 010)"
Based on the build of it I don't think I would have purchased it had I known. My E7 seems like a much better built product. I can't comment on the sound since I can't listen to it. If anyone has any ideas please let me know. I really don't want to have to ship it back to China.
I'm really bummed. I was really looking forward to this.
