I wanted a tool for the battery cap. change was a great idea so you are not without a screw driver. my fudge hands keep dropping the nickel. I tried a stubby screwdriver but the blade was too thin. the answer must be right in front of me. lot's of things with that edge but you can't spend them.

I use a key ring, fits more snugly than any coin (maybe Chinese coinage is thicker?)

Just came here to see how the rich people live. I am jealous.

HaHa - good one!

My sxmini has already lasted over 10 cartons of smokes that I would have bought if I were still doing the nasties. Stick a Goblin on there, and my home made elixers, and I am saving tons of money. Funny how spending a few bucks can lead to saving hundreds.;)

tc1, that was a mistake! dna40 is nothing but trouble. that is imo guys we don't need a war okay.

only certain people will get this joke. I wonder if they will come out with an amg version that has 1000 watts lol.

AMG M class? [emoji6]

I'm well aware of the issues some dna 40 chips have. I'm also aware that the rDNA has a 4 month warranty and the chip itself has a 1 year warranty. Those who experience problems have them right away. So if mine exhibits problems, I'll just get it replaced.

No war ... in fact, overall I think the SX Mini is the better device in many ways. I just couldn't resist the price and the fact that the VS is smaller started to appeal to me for some reason. Keep in mind as well, that we have no idea if their will be problems with the J chip either.

Like I said, I plan on buying a YiHi device eventually. I'm just hoping I can skip the M class and hope to baby jesus that they figure out kanthal temp control. THAT will probably be my next YiHi purchase. Heck who knows ... might be something even better around the corner. 2015 is going to be the year of regulated innovation IMHO.

2014 wasn't anything to sneeze at, either.

Moving so quickly that I can't even keep up.

I gotta say, I'd rather deal with the jumbled screen than the sx mini battery cap and subpar charging port.

I hear all the talk about the USB port, but I'm about to flip 1,000,000 Joules, and use the USB port to charge exclusively, and never had an issue (knock on wood).

They won't because it's physically impossible. Kanthal has a very stable resistance when heated (which is the whole point of it). You need pure metals (nickel, platinum, titanium, copper being the common ones). Without predictable resistance changes, you can't measure the temperature. That's why Evolv used nickel -- it's resistance changes based on heat are very linear and predictable up to about 600F (which just so happens to be the DNA-40 cut-off -- that was no accident).

Wikipedia has a decent entry on RTD's (resistance thermometers).

Hi guys,

You are all guilty of me spending more money and o won't forgive you :laugh:.....

Ok, now for real.... After reading this thread i made my decision and got me one to without temp. control since i'm very reluctant with using NICKEL for vaping. If they can make temp. control with kanthal i will give it try.
So far i'm loving it and during the next few days i will give it a good run. This device i bought to replace a provari so it has to be very good. I still have other devices to play around with but this one is going to be my daily driver. Thanks for all your input and opinions.......

Same here. I even purchased (see below) a super tiny 1A (1000mAh, twice the 500mAh of the SXmini and others)) micro USB board to change for a Sunday project, but mine just won't quit! LOL. I'll do it anyway once my M class arrives.

and just my $0.02, but @tc1, that was a mistake. For a savings of what would be just a few packs of cigarettes, a unit with a known problematic board/display and only 4-month warranty (that in itself shows the company doesn't believe in the quality), made by a cheap Chinese clone mfg (for Vapor Shark) vs a full one-year warranty, 150% - 300% more power, a YiHi chip and a great group of dealers.....to me, not even a choice/option.

You're assuming resistance is the only electrical property that could be linked to temperature. But is it? I'm wondering if you could send a radio signal through the wire and then somehow detect a change in it based on temperature?

Well, that would be something. Probably have to use the main deflector dish to bombard the coil with tachyons or something.

Regardless of your opinion, there are two facts:

1) Kanthal DOES change resistance when heated, albeit not to the extreme of nickel. And, like kbriggs stated, you're making one hell of an assumption that measuring resistance is the ONLY way to detect temperature change.

2) YiHi HAVE stated they ARE working on a kanthal temperature control solution. If it doesn't turn out to be reliable, we'll never see it. Their first priority is the new SXmini with SX350J. Their second priority is an update to the S-class to give it temperature control, if they can do it somewhat reliably. Their third priority is kanthal temperature control. Only time will tell - in the meantime, let's leave the opinions to the R&D engineers with actual knowledge and experience in the field.

And you certainly have a right to your opinion. I'm well aware of the drawbacks and pros to just about every device out on the market atm but at the end of the day it's my money and I made a decision based on my personal preferences.

$60 is $60 ... especially when you're bringing a new child into the world in 3 days. Had I not got a screaming deal on the rDNA, I would have waited another month or so and waited for the reviews of the SX Mini M ... most likely purchasing it. However, the more I thought about it, the more I decided I wanted a smaller mod, with step down, and the potential to explore temp control. Yes some people have issues with them (and at $190 I find that inexcusable) but there are also many people who love their DNA40 mods. So in the end I decided to grab a solid device, pocket the $60 for diapers, and look towards the future of perhaps even better technology YiHi will offer.

Maybe that's not an option for you, but it was certainly an option for me.

As far as quality and warranty goes. Most people don't complain about the build quality of VaporShark products. It is the DNA40 chip itself which has had problems, but Evolv has proven they stand by their 1 year warranty. I don't know WHO produces the boxes for VaporShark, nor do I know who YiHi is outsourcing theirs from. So speculating whether or not they come from a "cheap clone factory" seems irrelevant when comparing the two. I vape at 25-35 watts so either device would suffice when it comes to power. As far as supporting dealers ... there are many greater dealers out there that sell one or the other ... some even both.

So for me ... it came down to the rDNA being smaller and at a fantastic price. Both devices do what I want. (Both provide the power I require, step down, and will allow me to dabble in temp control)

I understand where you are coming from, just realize everyone has different tastes and opinions. I don't really bash many if any mods and I'm certainly not bashing the current lineup of Yihi mods. I just decided to put my money on YiHi on hold until I see that "SX Mini K Class". $60 is a nice savings to put in the diaper fund ....

...

To my dismay, I recently found out that my VS rDNA30 does not have voltage stepdown. I normally vape at 12 to 16 watts and with a low ohm coil (1 or less), I sometimes get a flashing ohm display indicating that the Evolve DNA30 chip can't output voltage low enough to achieve my wattage setting. Instead, the chip outputs whatever is my current battery voltage. This is probably not a problem for you since you vape at 25-35 watts, but I just wanted to point that out.

And congrats on the new baby!
