I ordered a black 510 batt with purple led from Rob late last week, then a USB passthru(again 510) on saturday. I got the battery on monday(wow fast shipping), but, unfortunately it was DOA(Hey, it happens). I called Rob on Monday morning and he actually answered the phone. I told him about the battery and he was just about to ship out my passthru, so he threw in a replacement battery at no charge. I just received today(again, wow fast shipping) both passthru and new working battery. Now that's what I call service above and beyond the call of duty.
