@t3mp3rz88 they are ok. Loke I,couldnt see a line until I put it under the,light and it didn't sit long at all. And I've seen them negavtive that is why I,think this would ne a line. I th I,k it didnt show up to well bc I barley had per amd it waant the fmu. But I mean if its a postive for sure then they work pretty well. Ive had negative ones and this is the first one that had a line Like this.
