My BX750MI-GR has saved my precious data on two occasions. Earlier this year, my seven year old, well used waffle iron shorted, popping loudly and sparking quite brightly in the process, probably because of all the gunk that had accumulated inside its less cleanable interior over the years. That not only made my breaker trip, but also blew the 16 amp main fuse. The UPS kicked in immediately, making a klick and a beep, which felt amazing. That was my first time ever.
As for the second time, see this post.
Yeah though I gave up on PvP mostly due to the cheating and some likely good players headshotting me from a position I couldn’t even fathom. So I PvE nowadays, just got my Kappa container for the first time, working on my first actual escape run.
