I recently purchased the v2 because it was supposed to be reusable after it shorts. Well, it worked flawlessly for one month and then suddenly, it shorted once on my mini vivi novas. Keep in mind that it only shorted once. After reading the VapeSafe 2 instructions and letting it cool down and reset itself, I placed the fuse back in the mod as usual and fired up my KTS mod with a fully charged AW 18350 battery. No vape came out, however, after sucking on the mod several times, a small amount of vape came out. I thought it was eventually going to kick in like it was working before the short, but no luck. True that it resetted itself, but what's the point if it isn't going to work at its full capacity. I contact the place where I bought the VapeSafe2 from and they contacted the manufacturer to see if they can replace my fuse. Unfortunately, they said that the fuse was constantly shorted several times and therefore, is no longer to work at it's full capacity. The fuse shorted ONLY ONCE and not several times, so their claim was inaccurate to begin with. Had I known that this was how this fuse performs I would've just bought the cheaper VapeSafe 1 instead, knowing that it was a 1 time fuse. If you think about it, VapeSafe2 is also a 1 time fuse...well, at least in my case it was a 1 time fuse.
So in short, don't buy the expensive v2 and just get the cheaper v1 of this fuse if you really must get a fuse to protect your mod and battery. I was robbed $15 + shipping ($4) this piece of .... fuse with crappy ... customer service and support. F THEM ......!!! hahahha....SORRY FOR CUSSING BUT THAT'S HOW I FEEL FOR THE MOMENT. PEACE OUT!!
