Cheaply made
The lighter did not stand up to regular use (lasted 6 months). It was a good idea to be able to use batteries instead of a USB charging system, because sometimes they aren't available. Like when you're out in the field. And now it's not available. Bottom line: Unit not constructed for regular use. 2 stars because I liked the concept of battery power....I already own the USB ones.
Rating: 2 stars
