    Hello I purchased a titanium bucket and a quartz bucket. I see the temp and wattage for the titanium but not for the Quartz. Sorry if I missed it… Can you please provide.?
    Also, I hope the titanium bucket produces thick vape clouds but if I am not satisfied, which one of the coil options would you recommend for the heaviest cloud production?
    Thanks very much for any feedback.

    • Vic says:

      The Quartz bucket uses the same settings pretty much. Kanthal coils are the heaviest hitters too. I personally prefer the Triple Ti though.

        Hey man, I recently bought one of these and I love it, but i’m having some issues with the TC mode with it with my mod (Smok Alien 220w). I have the atomizer locked at .7 ohms, and I set it for 400 degrees and 25watts, but anytime I try and hit it it only fires for about a second before it switches back to wattage mode. I just felt like it hauled a little bit better in TC mode so I wanna get back to using it in that mode as it kinda just suddenly stopped working after working fine in TC for a while

  • George says:

    I have a TAF with a bucket coil. I cannot tell what material it is. I have it connected to a Kanger 200W mod box. I set it to TC at 400F but I cannot produce any smoke even with 10 sec. pre-heat. The TAF works with another coil but does not with the bucket.
    I also tried the power setting at 28W with no results. Can you tell me what am I doing wrong. This has me stumped.

  • Jory says:

    Hi I was wondering about the settings for the Molacule coil are ? Thanks.

  • chris says:

    Hi I love the product but am a little confused and want to make sure I’m using it properly. I use the titanium bucket for rosin but am unsure what temperature to set it, as it appears to be heated by a ceramic donut from below. The ceramic donut settings are different than the titanium bucket settings, and donut just cracked so I have to replace it making me wonder if I’m running it too hot. When using the titanium bucket in a top airflow sai which settings should I use?

    • Vic says:

      You need to run the buckets in Temp Ni mode, at less than 25w. Starting temp should be about 400°.
      Go up 20° at a time if needed.

    Just bought the Sai Taf with top airflow and ti bucket. Got 2 additional coils with it I’d like to take for a test drive but am failing to understand how to remove the donut coil under the ti bucket that was preinstalled.

    Hoping you can help me, don’t want to force anything and damage the gear. Thank you for your assistance.

  • Mari W says:

    Hello! I’m really interested in this product because of all the reviews, but I’m a noob and not sure I understand the terminology around what all I need so I just want to be sure: This product is just the top which is the atomizer, and I would need to buy a battery separately, correct? It would need to be a battery with variable… temp settings? Wattage settings? Something else? Is there a particular battery you recommend that works best with the bucket setup?

    Thank you!!

    Vic, you have created something fantastic here.
    You’re right to love the triple titanium (just got the quartz wrapped one in the mail and I’m already ordering the ceramic tomorrow), but these buckets when tuned in right with tc are incredible….i’m shocked at the performance. Also love the molecule coil after getting all the hotspots out it slurps up oil like crazy and produces massive rips! I will buy anything you put out because you have figured it out my friend!
