Thought this was a great little tool, but went to make a presentation today and the laser didn't work. Was purchased on September 11, 2017. Way too soon for it to fail.

Batteries don't last very long (about two or three months) even when the laser is not used or even turned off.

Worked well for a month. After that the lights on the keypad wouldn't turn off depleting battery. Now I have to charge it every day, one of the many things I was trying to avoid with a simple cellphone. disappointed.

It was working for like 2 weeks, and after that it didn't play any dvd anymore! There should be a problem with its optic.

This was really great for the first few months, but it broke shortly after. The laser stopped working and changing the batteries did not fix the issue.

Light bar only worked for a month. Now the light flickers. All external connections are tight.

Was working fine, but last week every minute it detects a laser.  Happened on my route to and from work, It's really annoying.  I tried it again a few days ago and it seemed to be fine.  Not really sure what was going on.

When it worked, it lighted up.  One month before anniversary, it stopped working and I threw it in trash.

Update on Feb 1: seller was quick to respond and sent me replacement for free.  5-star for the service.

This laser would be awesome if it didn't fall apart with regular use.

I have tried placing two orders and gotten a dud both times.

My .223 laser bore sighter only worked for about a minute. I don't know if it was the batteries or the laser itself that died.

Laser/light option doesnt work. Only the laser or just the light.

I bought this lighting to inhance movie watching. Lights were great, but only after a month the remote just stopped working. Thought it was the battery so I even changed it and it still does not work. Doesnt make sense to have a remote go faulty after a month of non-consistent use.
