I have not ever been so lazy or pressed for time as to not be able to throw together a PB&J. I have had these and they are nothing spectacular... And absurdly expensive per unit in comparison to a loaf of bread, and a jar of peanut butter, and a jar of jelly... And I can vary the type of ingredients for variety- cherry jam and chunky peanut butter, Nutella and peanut butter, honey roasted peanut butter and jalapeno jelly...
The ones the school I work in make for sale are much better in quality. If I am really pinched for time, I can grab lunch in the cafeteria at work.
I get it is for convenience, but honestly, it takes maybe four minutes to make a sandwich. I pack my lunch every day and never spend more than five minutes putting it together and putting it all away.
To each their own, I guess, but to me, it's not worth it. I don't buy a ton of prepackaged convenience foods at all anymore.
