It's a user guide that's a small strip of paper that's folded about 5 times and just tries to explain the manual and auto settings.It's really not very good at expaining.
Reading the forum review and watching You Tube videos are much better
I bought three orders from 18650Battery this year- all 100% to spec. Then the Molicel P42a went from $7.50 to $5.99 each and I loaded up on my last order.
Also, I am in Kansas and to date: there are no interstate sales taxes (yet… tell that to Aliexpress who charges ALL 50 states a fake “tax” this year). Anyway, 18650Battery does NOT charge taxes to Kansas as they shouldn’t.
AND… their shipping is VERY fast (like two days or three at most) while also being reasonable too! I got 8 batteries a few weeks back (four of them Molicel 21700s) and the shipping was UNDER $6.
Shout out to these guys, they have rocked with the “daily specials” mixed into any order I’ve made— making buying from them about the best price anywhere for legit cells (and zero BS) that I’ve seen otherwise anywhere else.
PS. They always toss a few 18650 wraps in an order. I stored them until I shredded my Panny Bs in my LT1 lantern and so I was GLAD I had these wraps to fix all four (soldering “buttons” on them and re-wrapping them using the wify’s hair dryer to shrink them down)
