Had two major issues just out of the box. - Lyman Borecam Digital Borescope w/ Monitor

First I'll say that if the unit would have worked for more than a couple hours, I'd probably give it 4-5 stars. It's not nearly as nice of a picture as some of the higher price options but it's also only $200. The pictures are good enough to see bore damage and also if your cleaning regime is working.

That said my unit was DOA out of the box twice! First the power cable that goes between the USB power adapter and the display unit was dead, not a huge deal I had another micro USB cable around. Once that was replaced it worked pretty well for a couple hours, and then the light in the wand started flickering and just stopped working, but the camera continued to function, but without the light it's worthless. Not sure if it was the camera/wand unit, something in the cable, or the display unit.

So after two major issues out of the box, I sent it back for a refund.

If they put some more $ into it, making a better display, and higher quality parts, they could double the price to $400, and it would still be half the price of the next best option. The quality is really really lacking and it seems like people either get one that works, or is a total lemon like mine.
