Target brand vs frer rapid result

Does anyone know the sensitivity level of the frer rapid result. I've never used them before and didn't notice until after taking it that on the box it says to take it on the day of missed period or after, not the free usual "6 days sooner". Yesterday I took one of the new target brand tests and got a little something...Then today my husband went out and got me the frer rapid result and took that and got nothing. Wondering if they're just not as sensitive or maybe just got a dud from the target brand? Here's a pic of yesterday's target brand and then this morning's frer rapid result. Any info on the sensitivity level of the rapid result would be awesome. Any input on these two test would be great too thank you!
