Yes, I don't have one but they really aren't designed for longevity. Honestly, I would replace it with something more robust, like a pod mod system designed for refilling, something like the Joytech Penguin or Dolphin, perhaps. I'd say it may be the battery, depending on how often you needed to charge it, although it could be some kind of connection issue, hard to say.
Getting more durable and flexible vape gear would be a win, from my viewpoint. I like vape equipment that is durable and lasts.
You could also go to an AOI starter setup, or just a small MTL
tank and a decent battery (either an external, one battery mod like the newest Pico) or something that you can charge via USB with an internal battery that is more robust. I also tend to recommend a Zelos starter kit with a Nautilus 2 setup. Inexpensive, but fairly durable (mine is still going strong after 7 months, my husband now has it as his backup vape) and it's a fairly well-loved "'starter" MTL tank for many people.
Best of luck,
Anna
