HI THERE FOLKS, I BOUGHT A VISON SPINNER 2 BATTERY AS MY FIRST BUY, SO FAR I HAS WORKED WELL, BUT TODAY I TURNED IT ON, WHEN I WENT TO TURN IT OFF IT DOESNT. IT HAS A BLUE LIGHT ON, WHICH DOESNT WANNA GO OFF, BLINK, DO NOTHING. HAS ANYONE ENCOUNTERED A PROBLEM SIMILAR TO THIS WITH THIS BATTERY? I BOUGHT THAT SPINNER BECAUSE THEY TOLD ME TO OP FOR A VARIABLE TEMP SETTING, HOW DOES THAT WORK? DOES IT AFFECT THE TASTE, THE HIGH, DOES IT BURN MORE QUICKLY? ALSO, ARE THE CARTRIDGES SUPPOSED TO BE COMPLETLY EMPTY WHEN YOU ARE DONE WITH THEM? OR WILL IT HAVE SOME OIL STILL INSIDE THAT YOU CAN'T VAPE? WHAT BATTERIES DO YOU SUGGEST, (THIN, SMALL. DISCRETE) THANKS FOR YOUR TIME
