You get for what you pay for with this. It gets the job done nicely and saves you money compared to more expensive 510 thread batteries for vape pens. If you are looking to save a buck this will help you out.
Coming from using a safety pin and jar carb, this is a huge step up. It’s night and day. Makes me feel like a pro. Delivered in 4 days, no damage. I’m very pleased with this product. I’ll definitely order from this site again.
