Hey guys, I'm looking to get a vaporizer gift for a loved one who smokes both tobacco and medical flowers. From the reviews here, it seems like the pens that use flowers aren't as reliable or stealth looking, so I'm fine sticking to concentrates. That being said, which portable pen would be the best pick for both tobacco oil and dabs/concentrates? I'd like to keep it under $150, and the "stealthier" looking the better. Thanks!!
