It appears First Response has changed the test strip in their tests. They used to be just clear plastic but I had an evap/indent on one so I opened it up and this is what I found. It has some kind of coating on it, I think this is what had been causing all the evaps/indents lately. Really disappointing since they used to be so reliable!
