Don't lol, there ok, I use mine once in awhile. I thought it would be great but they just aren't easy to see anything with, like cracked HX or something. Just my opinion and maybe there are better than the Milwaukee I have.
I have a whistler from home depot and works great.
Has about a 4.5 inch color screen,
3 foot long... Hose, or whatever ya wanna call it,
Detachable screen which you can plug into a TV
You can spend more on 1 that records to an SD card
Dimmer on the screen
Adjustable light brightness for camera...
Great for spotting cracks around rivets.
I have a ridgid camera i purchased a few years ago. I dont know if they make mine anymore the screen is analog so its a little fuzzy compared to the new digital ones. I like it a lot its been very reliable and very helpful at times.
