Pregmate indents??

Has anyone had experience with indents on a pregmate strip? I had a chemical last month and barely got even the faintest line on this brand. I dipped one in water also and I’ll post those pics below my test with the vvvfl. Any stories or experiences with the quality of pregmate strips?

PS I know the line looks grey but it has color in person. I tweaked it a few times and barely noticed some color. It was taken within time frame.

I’m not sure what DPO I am but possibly 8?
