Wondfo VS Other internet cheapies

I wanted to share this bc i had ordered ovulation and pregnancy test strips from Amazon, the Healthywiser brand, and i never got a true positive opk. I would see it get darker than the other days and hust bd around then but worried maybe i was not ovulating every month I decided to get the Wondfo this month and I just wanted to share a photo of both test done at the same time from the same urine at the appropriate time limit. The blue test strip is the Wondfo the other is Healthywiser and as you can see the wondfo is clearly equal darkness where the pink test is not quite as dark, therefore not considered positive. I thought incase anyone else was having a hard time getting a clear positive with their opks as well or maybe this would save someone else the trouble.
