Plug readers

I'm no plug reader mark but the first ones look eroded or worn, unless they came that way.
I'm looking at the strap. Not seeing it on the electrode.

The second set is much sharper. Fresher plug?

Your camera shots are pretty good. Its hard to focus in small with most digitals.
If you can get a white background in sunlight, that's the best for color ref.
Except, that the digital camara sometimes assume the metering based on the white surface. And of course metering should be on neutral gray or it will be off...

And yea I'm still using Champions, but do inspect each one for strap attachment or anything else that could be poorly manufactured. Quality is definately blah.
