i havent gotten LR from them but I have heard good things about the quality of the rock, and I need rock so this is win win for me.I have a tank almost ready for the rock and a bunch of water premixed, I'm going to yank my aqua c remora off my DT to go on the cure tank. with the weather being what it is around here, LR will best be able to handle the extremes I didnt really want to risk anything else. I know SWF.com has a replacement policy for DOA but I know the pony express up here in maine (there is actually a ups driver that rides around on a bicycle pulling a cart even in the winter) I see him in my neighbor hood all the time wich is why I use fed ex unless someone requests UPS. could you imagine live coral or fish toting around in the back of an open cart on a 10degree day for 5 hours with a wind chill -3 no matter how well packed I just dont trust it.
