Mine showed up today. Immediately installed the 2.0 update and threw a known-good (and cold) Ti01 tank on it, locked resistance, and started vaping. Vape production compared to an ipv D2 or SX Mini M is not great, need to crank temps up over 520f to get close to what a Yihi board gives me at 450f, and even that tapers off quickly, about a second or two of good vaping before power is cut drastically, in my typical 4-5 second pulls. Same tank (Bellus, 26ga 2.0mm ID dual Unkamen titanium, 9 wraps each), once cooled down and locked on the D2 vaped like a dream again.

Same tank on a DNA40 Flask, set to 340f, vaped great too, so it's not all down to how Yihi handles power when the temp limit is reached. I'll dink around with the TCR settings later, maybe the default titanium TCR between the Yihis and the Stout is different, and I'll try downgrading to 1.1 if that doesn't help.

All three buttons are wobbly and very noisy in normal use, increasing to maraca-level rattle when shake-testing it. Hell, even Smok or Cloupor would be ashamed of rattle that bad. Nice metal buttons though.

Feels nice in the hand, and with an 18650 doesn't feel much heavier than my IPV D2 (and it's not much larger). And of course, it's lighter than my SX Mini M Class.

Battery door is slick, though the noise it makes when sitting it on a table is a bit disconcerting. 18650 adapter rattled like crazy (side to side a bit, and up and down a lot) until I wrapped some electrical tape around it to increase friction. Quiet now, and works fine. Still waiting on Mooch results before investing in 26650s, and I have a nice supply of 3000mAh LG and Samsung 18650s to tide me over.

Good news is, I won this in a giveaway, so I'm not at all upset, and I can see where a non-rattly, good vaping example would be a great mod. But had I dropped $90 on it, I reckon I would be upset, and working on a refund or replacement. FYI, it's a retail unit, not a sample.

Huh, that's funny. I found the vape experience to be identical to my DNA200 mod (VT200) using a SubTank Mini with the NI200 coil head. Same resistance, same wattage, and the same temp settings on both.

Like you though, I was expecting MUCH more for my money. Especially after seeing PBusardo's wideo with the VF guy. Poor fit on the battery adapter is annoying and I agree about how it sounds "loose" when setting it down.

In the beginning I had planned on getting the VF Lite also in stainless but I think I'll pass for now...

I also received my Silver today and I would have to agree with Croak, the hollow sound it makes is a when you put it down is a little weird. The buttons on both of mine are nice and tight.

I've got the Billow V2 on it with a .29 kanthal build at 29.3W and it's performing nicely. I haven't done the update on mine yet.

Croak, I threw thicker O-rings on mine and it killed the rattle with the 18650 tube.

They should have never made the tube. The device was designed to fit a 26650 battery and they should have left it at that. Why make the lite if the stout was supposed service both size batteries.
Still having intermittent issues with the fire button not not working. I had the problem with the first and now with the second. Maybe it can fixed with a software update.
Not returning the device again . I ordered this device on Christmas Eve and have only used it for 5 days between the back and forth.
Maybe the next iteration will be better.

Naw, I think the tube was a great idea, a piece that cost pennies to include that gives the owner more options. And since I was able to start vaping with it right away, having gotten rid of my 26650s almost a year ago, it's already proven itself to me.

I made a 0.038 TCR preset, and it's vaping my titanium builds better now, at least its not tailing off drastically like it does with the factory Ti preset. Still not happy with the buttons...I can live with rattle when it's shook, but rattle and wobble just using the device annoys me to no end. Gonna contact VF and see if I have a shot at a replacement, and if not, I'll see about tearing it down and padding the buttons, though I suspect tearing this one down won't be easy.

    The 26650 testing is done!

    There are some great choices for the VF Stout. Luckily, the highest performing 26650's are also the shortest in length so they will fit in our Stouts. Here are my recommendations...
    • Basen Black 4500mAh
    • Brillipower Green 80A 4500mAh
    • Efest Green 20A 4200mAh
    • MXJO Yellow 35A 3500mAh
    All of the above batteries appear to use the same cell under the wrap so you can buy any of them. The MXJO has a lower capacity than the others though. I do not know why.

    CAUTION: These battery companies can change what is used under the wrap at any time! But without any 26650's being available from Samsung, Sony, or LG we're stuck using whatever these other companies offer.

    Seriously- you have a problem with cautionary info being repeated?

    I don't but I believe that it needs to be appropriate to the device and it doesn't need to be repeated multiple times in a thread. It appears to me that the device itself is being targeted.

    There are many single cell 18650 devices that go to 75W, dual 18650 devices that go to 200W or beyond that are being discussed in several threads that we are a;; participating in.

    Like mechs, high wattage regulated devices whether it be single cell, dual cell or 26650 no one talks about the responsibility of the user or how a device can be used safely.

    This from another thread:

    But you'd agree that going up to 100w on any of these batteries is not the best of ideas?

    And the response:

    Actually, any of these four easily handle 40A pulses (5 sec on/30 sec off) and only rise up to about 60°C if discharged all the way down to 2.5V. In a Stout they would probably only hit about 55°C°C due to the 2.9V cutoff.

    The run time wouldn't be very good at 100W but certainly better than any 18650. At 100W you're above the CDR of all four of them but these 26650's just have their voltages crash instead of overheating if run too hard. They might get damaged some if the mod autofired at 100W but I don't think they would heat up anywhere near hot enough to vent.

    I will have to finish the continuous current testing to know for sure.

    Having the information, good accurate information for our community is important. Just going into thread with a "sky is falling" proclamation without data doesn't help anyone.

    I appreciate the feedback but I would respectfully disagree given the amount of threads the same "sky is falling" posts are being made regarding this specific device when the problem is much larger.

    Again, 75 watts on a single 18650, 220+ watts on dual 18650s.

    There are some excellent threads, conversation and supporting information/resources going on right now discussing regulated devices and the claims manufacturers are making about the device. These topics are more than "this is dangerous".

    Personally I read them all to gain knowledge and so that I can speak using that knowledge and add supporting information. Anything less I would consider scuttlebutt, someone just making claims that they either do not have the knowledge or insight to support.

    Fantastic!
    A bit surprised about the 4500 AWT yellows. Thought they were going to be really bad...

    Cobalt, I'm all about safety and you and I could dance on this topic for a while. I'm all about engaging someone in a healthy discussion.

    If you read Mooch's post about 26650's they can be used at 100W in the device. That being said it's not advisable but neither is using a mech at .1 ohms which people continue to do after being told it's not smart.

    My point is this, everyone shares a responsibility in using devices safely. Many manufacturers are building devices and marketing them aggressively. The DNA chip is a 200W device and people are putting them into devices with dual 18650's. We really have just begin to scratch the surface on safe LIPO batteries.

    People make statements all the time without knowledge or providing supporting information. At times they just keep repeating the same thing all over the site and on multiple threads. I just don't believe it helps the membership or our community to make comments (unless it's opinion) about something without providing the education to go with it.

    Also focusing on a single device and making sure you post repeatedly the same information in all of the product threads really isn't helping.

    Like I already mentioned the problem isn't just what this device is capable of it's many devices that are being released that share the same profile. Chips are being added to devices and marketed beyond the batteries capacity.

    Mooch, you da man!! Thanx for all you do for us!

    As I stated a few days ago, the green Efest's have been performing very well for me and continue to do so. They are also one of the shorter ones and fit nicely in the Stout.

    Once again Mooch, thanx for your hard work!!

    LOL...so did I!
    They did fundamentally better than last time. Must have changed the cell or the batch I tested previously was a much lower grade.
