Sometimes it's just the way it hits, although I drop my mods all the time honestly and have never broken one at ALL. My very first MVP mod has some considerable dents in it but it still works. I retired it more because it chewed through my battery wraps.
Apart from glass which should I be unlucky enough to be facing it in a tank I immediately look for metal cages (unless it's like something like the Innoken Zenith with a fair bit of protection) or non glass tanks that fit. The worst was quartz glass, thank you Zen/HOH it was SUPER luxurious and I think you knew about it's durability so thank you for including a plastic tank for folks like me, but I shattered that stuff by looking at it cross eyed. But yeah, apart from the glass issue it is usually my tanks that die, although to be fair, for the most part, I am looking at you, Ego Mega series of tanks. They hate me. All joytech equipment hates me.
Joytech asked me to review some stuff and I gave them my standard "But I suck at reviews" disclaimer coupled to, "Besides, they way your and I's stuff works together, and let me be clear it is MY fault, not yours, I'd need like 3 sets of gear to get through the review period."
LOL I do not think they will ask again.
