I got one of my MVPs from 101vape and one from ebay (101 was out of stock when I went back to get a second one). Had identical good experiences with both and got a genuine product both times. Just be aware that neither ebay nor paypal like e-cig related items, so don't mention ecigs, personal vaporizers, or anything that could remotely be construed as vaping related when making purchases through either service. I've found it best not to mention anything at all, in fact... there's no reason to put anything in the paypal comments section, and a simple "fast shipping, thank you" or "good seller" works for ebay feedback.
