A christmas present that failed out of the box... - NcSTAR Micro Tactical Green Dot Sight w/ On/Off Switch

My wife bought this at full retail price for me a few years ago. I decided to finally mount the unit on my Model 41 S&W. Out of the box, it would not turn on. Replaced the battery thinking it might be "toast" and noticed that the wiring coming from under the battery PCB was damaged from lack of clearance via the routing and machining tolerances. I am an associate engineer with 25 years in R&D and I have never seen worse engineering on a product. The unit will turn on with the lower mounting portion not in place. As soon as you put the two halves together the LED turns off. I thought about sending it in for $10 S&H fee, but then I read the reviews... unless there has been a revision in the design it appears this would be wasted time, money and effort. NcStar has lost a customer.
