Amazing for Halloween swamp show

This is not meant for continuous use. I had two of them in my garage to let me know where to stop the cars driving in. The garage door opener lamp socket powered them so they're only on when the door opens and for about 5 minutes. One failed after about 6 weeks and the other failed 1 week later. Now there is a faint green glow at the lens when powered on. Don't buy this product.

Is what I ordered

Item is exactly as I expected.

Bought 2 of these for a Halloween display and one did not work. The other one seemed to work great but I didn't get the effect I wanted.

I connected this up and used it once for 5min. Came back a month later, turned it on only to have a very dim laser. Not even bright enough to see it project the light. Very dissatisfied as it looked like it would be a nice unit. Not sure what to do now :(.

i did work only two minutes then it went off and did not come back on.. is a shame to have spent that money.

It must be plugged in to work. short cord - no on/off switch... not useful for me at all
