Avoid categories where a lot of items have fake specs (storage devices, LED bulbs, anything that claims a runtime on a Li-Ion battery)
I’d say be aware rather than avoid. E.g I bought a $10 camping lantern that claimed 2.5 times its true capacity, but it still runs for hours and is a great, well designed, if flimsy, product for the price.
floppy drive, hard drive, sechs drive — we got building blocks. Crowd sourcing a joke could work.
