I recently took a ton of First response early tests and had tons of what we thought were VVFLs but I think may have been evaps or indents ...

Just took this First response Rapid Results test and wondering if this is a evap/indent as well, or a VVFL. Just wanted to know if these tests are known for bad evaps or if anyone had photos of their evaps so I can tell the difference between them and a vvfl. Thanks so much
