Love the new Diamond series shhorty batts. Bought 2 x black with purple leds, 2 x matte black with blue leds, 2 x white with purple, 2 x white with blue. No problems with any except the black with purples leds. 
One stopped working properly within a couple of days. It was replaced by the good folk at V4L and I also bought a 3rd one. Now another one has started to malfunction. Every so often it doesn't work on an inhale or two, then works again. It's quite intermittent but happens at least 2-3 times per vape session. I've tried resetting the post, have done this a few times, makes no difference to the problem at all. I also find them quite 'airy' to use, perhaps sticking a needle in the holes to raise the post has widened the holes?
I love these batts, so am considering trying another variation, perhaps the matte black with purple leds, or just sticking with the blue leds.
Wondering if anyone else has the diamond series shorty black with purple leds, whether they have had any problems or they work fine? And if anyone has the matte blacks with purple leds, if they have had any issues?
