I ordered my first 510 from Innovapor on Monday night. It came Thursday. I opened the box and almost immediately realized I had ordered the USB adapter instead of the charger. Whoops!! I sent them an email asking if there was anyway to have one overnighted, shortly after, maybe half an hour later, my phone rings. It's Innovapor on the line saying that I probably don't want to pay the $24 shipping for $10 part. Indeed I did not! We got it all sorted out and I expect to see the charger in box on Saturday or perhaps Monday at the latest. Thanks again for the great service!!
