I thought I loved my 510 and since my sister got some mod stuff from Madvapes I found out it was the 510 atty on my mod box I loved. Then just when I made my 2nd mod box she my sister again purchased some mod parts. And now I've found it`s my 510 atty on my Flashlight mod that I really Love. Wow. I`m truly amazed at this mod. All I can think now is making more and more and more. I must have one of each color I`m starting to think I` ve caught modites or something. Thanks for the great Items at Madvapes. I`m so happy I could cry.
