I realize this is one of the most expensive mods available, but you need to realize what you’re getting with the Flaskman from Vapor Flask.
This is a DNA40 chip. It is currently the best chip on the market in my opinion in terms of consistency and features. You have options on the chip for temperature control if you use non-resistance wire. 40 Watts is plenty of power and this is a top of the line device.
The Flaskman is made of 6061 aluminum which is durable and still keeps the overall weight down. The flask-like shape fits easily and comfortably in your pocket and makes vaping the device and absolute joy. It feels good in the hand and the snow-white finish is absolutely gorgeous!
The key here is the Flaskman is powered by 2 18650 batteries. This means your charge and consistency will last a considerable time depending on you vape routine.
It is the top of the line. Period. You get your money’s worth with this device. I realize the price is high, but if it is really a problem and you still want a DNA40 device, you might have a look at the Vaporshark rDNA40. Its a top of the line device with the main difference being the single battery as opposed to dual batteries.
If you want the best and want a mod that will be reliable for a long time, I believe this is the one to go for.
