Well, one bad mod doesn't spoil a whole batch. There are mistakes made on EVERY high-volume assembly line. Many users report (including me) perfect function from Smok or Wotofo products (made by the same manufacturer, along with a couple much smaller mod brands)

Most likely a simple fix, such as no battery connection/looseness in the battery bay, or poor 510 good drop could cause either one to become a critical issue.

Unfortunately what you are describing is poor build quality, and, judging by the number of failures of Smok products (particularly the Rigel mods) its considerably more than one bad mod in a batch.

It could be a simple fix, but that is cold comfort if it craps out when you aren't at home.
