I purchased this lamp as a birthday present for my boss. Well when she opened it would not turn on. Pretty humiliating to say the least. Well looking at it I could see the manufacturer had not installed all the battery connectors making the lamp inoperable.(I am referring to the little springs that the batteries press against to form the electrical circuit.) For such a small low cost item it was not worth time/trouble to me to return the lamp and get a new one weeks later only to give my boss a seriously belated gift. So I was able to take apart a small LED utility lamp I had at my desk to scavenge a connector to replaced the missing on. I installed it in this Rangers lamp an viola it worked. Of course I am now with out my LED light that I had use for parts. Do not buy these lamps, who ever Amazon has building them is not doing a very good job, and in the process making them look bad.
