do any suppliers out there really make pro-active statements regarding sub-ohms? seems to me that'd be a legal minefield, particularly with the present political landscape surrounding vaping. i could envision a certain modmaster possibly adding additional safety features (fuses, for example) that may or may not help the sub-ohm crowd, or something along those lines, but that would about be it would be my guess.
of course i'm no attorney and i've never even once stayed at a holiday inn express...
Very good point. And, as far as taking best care of "the masses" I lean towards the simplicity of the mechanical spring, as far as durability and soundness, what we love so in our REOs, I lean toward the spring, and as far as cost short and long term, I lean towards spring. That's not to say I din't use fuse with some of my RBAs, especially in Woodvils that require soldering to replace a spring. Also, and I don't know, are there any mod fuses out there that can handle (and fit in a mod) the extreme stresses a
few are subjecting their mods to?
BTW... I haven't had a spring collapse in over two years but have averted some by simple testing before putting most juice heaters on my REOs. The majority of my spring collapses were defective atty/carto; a defective atty on my first 2010 Grand where the battery was a
protected (before AW IMRs came on the scene), the spring did not collapse, but the button melted some, defective cartos, mostly Resurectors, and when buttons stuck on and I wasn't paying attention,
totally user error.
In our outrageously litigious society developer and/or maker of just about anything has to be extremely mindful of legal responsibility. I recently heard on news that one municipality, not sure if city, county, or state, was going to, and may have, pass a law that held the person who texted someone driving, and driver had accident while texting with that person, that person would be held just as responsible for the accident as driver.

Or bad guy, armed with gun, sneaks into my house when I'm here, with big dogs barking at him outside, and no way to miss dog ruckus inside, he then hurts himself on my property fleeing the dogs (they didn't even have to bite) and then I'm sued for damages to his person and his emotional duress. And in some cases courts will rule in his favor. Best ending for me, in US, is that I'm out only for my legal fees, if he doesn't win, and I didn't have to shoot him.
