Gone through more mods than I can count over the years and none hold up for me, I am a machanic in cheese manufacturing and they get dropped, wet etc. my last mod was a Smok something I can’t remember and it was held together with epoxy cause it’s been dropped so many times, one before it just quit working always said batteries were dead and I had another that said low atomizer or something . I just got the Aegis solo as I wanted something smaller and now that I’m using a horizon falcon king (love this tank) I don’t need the higher wattages anymore. So far I’m happy
