I think I put the batteries in wrong.

My previous review was
"If failed out of the box.  I tried it with known good batteries.  it does not work.  I'm annoyed."

They allowed me to return it for a full refund, and I bought another one.

I bought a second one, and it did not work..... till I put the batteries in correctly.  I'm not 100% sure but I bet that's what happened.
