I agree completely with you. I have the same kit. And i love it. The size and performance are just great.
Also since you've been buying your vape gear from one shop for 4 years i think they'll be happy to help such a long time customer, i know i would if i had a business.
And you seem to take good care of your vape gear so don't overthink it. It's all stuff... And stuff wears out even if you treat it very well.
And i really didn't help you with anything except mentioning the obvious. [emoji14]
Have a great weekend jen
