Good practice with some fun - LaserLyte Steel Tyme Trainer Target

I was afraid they would never be available since they were on back-order for so long. They are small, perfect size for those of us who believe in "aim small...group small." The only problem was one, right out of the box, would continually "ping & flash" when placed in any light. It worked fine if it was set in a darkened room or corner; and for now that was bearable since we will hide these around the house and practice tactically clearing rooms. What else to do till the next season of GOT?
In hopes of correcting it I contacted Laserlyte who advised that the sensitivity could not be adjusted. They also suggested fresh batteries...I did mention "right out of the box"...right? Bottom line though, they were very kind and offered to replace it immediately. I'll be doing that this weekend.
I do highly recommend these as they are a great way to practice sight picture and trigger control with the ease of flipping on a switch....and fresh batteries.
