It is simply packed - without manual - but because self-explanatory that to me is OK.
The feel is great. You have a device in your hand, which makes a high impression.
Because the lamp is supplied with neither battery nor with charger I needed like.
I chose this set of 2 18650 batteries of 3000 mA and the option to use the charger with batteries inserted as Power Bank for USB devices .:
PSC = 1
(Which I can also recommend. Double charger, battery and the same battery for 36 Euro)
After charging screwed the bulb and inserted a battery. How many "Vorschreiberr" mentioned - the threads of the battery compartment when it drags a bit and screws should be lubricated.
Then turned and ---- JAAAA - amazed how bright and wide it lights. I have not measured it, but compared to my previous lamps illuminate when the neighboring buildings you exceed my "old" and my expectations.
And that can be expected at a price of "entry-level".
By contrast, plays (no lights) it is in a league which would justify a multiple price.
