I have the Gen too. And I read about this problem while researching it before buying but I got one anyway.
I figured it was probably due to people over tightening. I have been careful to not do that and 6 months down Iāve had 0 problems. I just screw my RTA in until I feel it hitting the end and donāt tighten it at all. It stays on.
I have lots of older mods with press fit 510 connections. None have popped out on me. Some Iāve been using for several years. I think as long as youāre not using unnecessary torque, you should be fine. Also, people pulling tight-ish RDA caps off while itās attached to a mod isnāt a great plan. Wismec Predator is the first mod I heard of that had a very lousy press fit 510 connection. The early GEN videos warned people about this one too.
I always tighten my RTAs together by hand as well. Iām always playing musical atties on my mods and never had any trouble with longevity.
I do like other styles of 510 connections better but press fit has been fine too. A lot my mods have screws from the top anchoring them down, Smoant Cylon types. Thereās also the ones that have the the threading built right into the mod casing, Smoant Battlestar types.
