Does it say PIPER on it? that's the maker of the one I have. USB, 3 different volts. I found the case it came it great.
I dont like it sadly,
but going to keep it as a very cheap backup
device as I only currently have a KGO kit; while pondering a VV box mod.
It's a fine simple backup,
but for me, could never be a use-all-day at the computer type
device. just my 2cents.
darkcityvapor.com - had a very nice chat with them the weekend they opened not too long ago, and picked one up from there for $15 or so.
Would I pay $15-20 for another one (with the very nice hard case it came in) ? - yes
would I pay $25 for it? nope
