What are the worst cons you can think of with everyday household items?

Hello everyone! I hope yall are doing well! I am trying to figure out what are household/everyday items we use and what are things that make it difficult/unconventional and in general what could be better about them? I ask bc i recently was thinking about how scrub daddy franchise got so big and why and it got me thinking, is there such item that is a completely different item that I can do essentially the same type thing with? Possibly anyway hehe
