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.
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 ....
