Yes. There have been 2 issues with my b.blaster 1000 and they have been excellent at shipping out replacement parts asap. My two issues were the screws rusting(they shipped new set of screws and a new volute), and the second issue was the impeller randomly stopping. I took it apart and there were no apparent issues. They sent' me a new impeller with some modifications to it, one of which is a smaller(in diameter) pinwheel. It works great with no issues. Thanks Jeremy!
