Femto BF - Frequently Asked Questions

Femto FAQ
  • Q1. The regular positive pin is missing. / I want to use my Femto-BF on a MOD which isn’t a squonker (BF MOD).
  • The main concept of Femto-BF is being used as a squonker. A regular positive pin isn’t contained in the original package however, we are selling a regular positive pin as an option.

  • Q2. I get liquid leaking when I charge the juice by pushing the BF juice bottle.
  • In order to make the inner space very narrow, the juice well of Femto-BF is made almost only for the wick (cotton). Therefore, it possibly gets leaked easily when you push the BF juice bottle as strong as you usually do for the other RDAs. Please push the BF bottle softly to make cotton gets wet with the e-juice.

  • Q3. I want to disassemble every part to wash up. How can I take the center bottom air hole from the black peek deck?
  • Please do not take it off. The center bottom air hole is press-fitted. It will hardly be fixed or in the worst case, will not be fixed if you take it off forcibly. This is really unfortunate but we will be unable to help you with this issue.

  • Q4. Why is the cap threaded instead of O-ring to fit with the deck?
  • We suppose that the ordinary caps of RDAs are set by o-rings which are easy for taking off and dripping ejuice smooth. The threaded cap is to be more concentrated on being prepared for the leaking risk because Femto-BF is less needed to be juice charged by dripping.
