I'll just go ahead and say it.
The SX350 makes the DNA30 seem dated at this point. It has multiple features the DNA30 doesn't, and the only semi-valid excuse to not use one will be taken away when they enable
wattage up/down buttons in the next update scheduled for mid-June.
It's designed from the ground up to be a 50W chip. Polarity protection. True buck circuitry that can regulate down to 1.5v. .2Ω floor. Upgradeable via USB updates. Variable voltage as well as variable wattage. Bypass Mode making it a mech MOD with all of the protections of a regulated MOD. What most consider a better screen with real-time battery information. And all of these functions perform just as they should.
The DNA30 really isn't all that close. Evolv has some serious work to do if they want to stay competitive. A simple attage upgrade isn't going to do the job.
The only problem is that there are only two commercial models right now that have the SX350 chip:
a HUGE 26650 MOD that could bludgeon somebody pretty good, and a super expensive box MOD. You could look around various Facebook groups or eBay right now and buy one made by a modder, but they're going to be expensive too.
