I am vendor loyal if I have gotten good service and prices (these are mostly multi-brand good-price hardware vendors like Liberty-Flights.com and LiteCigUSA.net)
I am model loyal no matter which vendor I buy it from
I am anti-clone unless I know the clone is well made, well liked, and totally compatible with the original manufacturer model.
I am viciously anti anything that is called one model number but has different threading or polarity (vicious like a badger) and for some models that have that problem I steer people totally away from clones
I am anti ripoff rebranders, especially those that charge too much for parts, lie, do not sell blank cartridges, sell prefills that are glued shut to thwart adding juice, or sell bad models
I am fine with reasonably priced rebranders that offer nice colors and full service w/ juice, blank cartridges and good service though if we don't know what model it is then I will warn people against it
I have an attitude about places that don't offer manual batteries
