I got this for the missus. She likes the single 18650 mod for mobility. This is very well build and easy to operate. Battery fit snig, back fits solid with no rattles etc. As for the Fingerprint function, she is useless at using it on her phone, nothing picks her finger up. So, before purches, I made sure we could disable it. This is possible and she was happy with that.
Finally, this is a good compact mod and would recommend. Thanks Vapping101
