Hi Casey;
As I believe Surfmonkey brought up in another
thread, are these 510 LR atty's actually manufactured by
joyetech(the originator of the 510 product line) or are these 510 LR atty's "knock off's" produced by another manufacturer. Either way, I'm sure they work well(I have purchased LR atty's from other sellers that I know are NOT genuine Joye and have not had a problem with them). I would, however, feel slightly more inclined towards buying a genuine Joye 510 LR atty seeing that they are the innovator company and they have a fairly good rep.
Thanks
