So I have initiated the batteries in the lamp and tried to turn on ..
Nothing happened, so I pressed several times on the switch, inserted other batteries ...
After about 12 times turn she went so but at last.
Too early happy: After about 6 seconds it goes out and simply can then also not the same on again, but you must again about 10 times the switch.
When the lamp is on and one switch in the turbo mode, it is also made after 4 seconds.
Real shame that would have been LAMP)
The return shipping was super easy and hassle free.
But kudos for Amazon
For the money you can rather buy another lamp ..
