I wouldnt say to definately go with the dna200. Worked my way up from a
smok m80 to xcube2, and bought a spare d2. I like fiddling with my mods so I bought an efusion dna200.
The efusion dna200 has consistent firing. Love it from the day I bought it. Fast charging. I dont have to take out the battery and charge it. Just simply plug in with USB cable from your mobile charger. Vuala.
But recently my chip showed "Warranty Service". Contacted evolv and they said its out of calibration and told me to send the device to them and they will replace my chip. Sounds great right? Not so great when you know you aint getting it back due to some restriction reasons.
Now my dna200 is laying eggs. Thinking about getting the wismec rx200. The 3 18650 and price is quite a steal. Plus, upgradeable firmware. That is definately a must for me.
Tbh, if it werent for the dna chip failing on me, I wouldnt have thought of buying another mod.
