“I absolutely love how discrete the pen is compared to vape pens you don't know that it's an herb pen unless you're close enough to smell. However, I've been buying/using these pins for the last couple of years & the batteries have taken a nosedive! Seems u get half the life out of them as you use to "around 1 month or 2" when I use to get 4 to 5... I'd gladly pay more for better quality! Hence the 3 star review.”
