Cheapo LED Flashlights --- Battery Hogs?

I have received as a promotion gift one device that, had I put it in service, would have eaten batteries like a hog... You see, it never shut off. Insted of on/off it was Bright/Dim. Since it was worth less than I paid for it and I did not pay for it (it was free) it hit the trash can and an E-mail to the folks who sent it telling them what I thought of it and suggesting they no longer offer it.

Your el-cheapos may have this problem.

I have several LED flashlights. and the one thing they seem to do is run a long long time on very little battery.
